With the continuous growth of global energy demand, the demand for graphite as an anode material for lithium-ion batteries (LIBs) has increased significantly. However, the large volume of end-of-life LIBs generates substantial amounts of retired graphite, which not only poses potential environmental risks but also raises challenges for strategic resource security, making its standardized management an urgent issue. This review focuses on the recycling and reuse of graphite from retired LIBs, systematically summarizing the core stages of the recovery process, including battery disassembly, graphite separation and purification, and strategies for restoring the performance of regenerated graphite. Key technologies, such as mechanical disassembly, hydrometallurgical/pyrometallurgical treatment, acid leaching, graphitization, flash joule heating, microwave treatment, and carbon coating, are analyzed in terms of their advantages and limitations, with discussion on effective approaches to enhance the electrochemical performance, structural repair, and cycling stability of regenerated graphite. Despite significant progress in graphite recycling and regeneration, several research gaps remain, such as the unclear quantitative relationship between defect repair efficiency and energy input during regeneration, which hinders precise process control, and the heterogeneity of retired graphite from different sources, which limits the adaptability of existing technologies. Furthermore, the industrial-scale application of regeneration technologies and the precise regeneration of various types of graphite are expected to be key research directions. These advances will facilitate the closed-loop utilization of LIBs materials, ensure strategic resource supply, and contribute to the development of sustainable energy.

随着全球能源需求的持续增长，石墨作为锂离子电池负极材料的需求量大幅增加。然而，大量报废的锂电池产生了大量的退役石墨，不仅存在潜在的环境风险，而且对战略资源安全提出了挑战，使其标准化管理成为一个迫切需要解决的问题。本文综述了退役锂电池中石墨的回收再利用，系统地总结了回收过程的核心阶段，包括电池拆解、石墨分离和纯化，以及恢复再生石墨性能的策略。分析了机械拆卸、湿法/火法处理、酸浸、石墨化、闪蒸焦耳加热、微波处理、碳包覆等关键技术的优缺点，探讨了提高再生石墨电化学性能、结构修复和循环稳定性的有效途径。尽管石墨回收再生技术取得了重大进展，但仍存在一些研究空白，如缺陷修复效率与再生过程中能量输入之间的定量关系不明确，这阻碍了精确的过程控制，以及不同来源的退役石墨的非均质性限制了现有技术的适应性。此外，再生技术的工业规模应用和各种类型石墨的精确再生有望成为重点研究方向。这些进展将促进lib材料的闭环利用，确保战略性资源供应，并为可持续能源的发展做出贡献。

Ammonium sulfate wastewater is a common type of industrial wastewater. Its sources are extensive and its composition is complex. Traditional treatment methods have problems such as low treatment efficiency and secondary pollution. Compared with these methods, electrodialysis (ED) technology has advantages such as high separation efficiency, no phase change and good stability. Therefore, ED technology shows a promising application prospect in the treatment of ammonium sulfate wastewater. However, ion-exchange membranes (IEM) have problems such as low selectivity, easy contamination and poor stability. These are the difficulties in its industrial promotion. For this reason, this paper focuses on the ammonium sulfate wastewater treatment system and delves deeply into the performance bottlenecks of IEM. This paper also systematically reviews the research progress of three mainstream modification strategies: surface coatings, interfacial polymerization (IP), and organic/inorganic composites. At the same time, this paper also analyzes its potential in enhancing membrane selectivity, anti-pollution performance and operational stability. This paper provides a theoretical basis and modification path for constructing high-performance IEM suitable for ammonium sulfate wastewater systems, thereby promoting the large-scale application of ED technology in this field.

硫酸铵废水是一种常见的工业废水。其来源广泛，构成复杂。传统的处理方法存在处理效率低、二次污染等问题。与这些方法相比，电渗析（ED）技术具有分离效率高、无相变、稳定性好等优点。因此，ED技术在处理硫酸铵废水中具有广阔的应用前景。但离子交换膜存在选择性低、易污染、稳定性差等问题。这些都是其产业推广的难点。为此，本文以硫酸铵废水处理系统为研究对象，深入探讨了IEM的性能瓶颈。本文还系统综述了三种主流改性策略的研究进展：表面涂层、界面聚合（IP）和有机/无机复合材料。同时分析了其在提高膜选择性、抗污染性能和运行稳定性方面的潜力。本文为构建适用于硫酸铵废水系统的高性能IEM提供了理论依据和改进路径，从而促进ED技术在该领域的大规模应用。

Energy harvesting is a promising approach to minimizing the impact of climate change and the levels of harmful gases in the environment. The development of a promising material with strong energy-harvesting properties makes energy harvesting more viable and a suitable option for protecting the environment and meeting the world's energy needs. The MXene quantum dots are a promising choice as an energy harvesting material due to their higher stability, electrical conductivity, and the presence of a large number of active sites at their interface to provide higher reactive spots to the material to convert the maximum amount of greenhouse gases into valuable products, such as ammonia, methane, and carbon dioxide. Additionally, the surface functional group modification at the MQD interface provided a synergistic benefit, improving their harvesting capability. The MQD's size-confinement effect altered their energy-harvesting performance compared to their nanosheets. The larger nanosheets have fewer active sites than the MQDs, resulting in reduced energy-harvesting characteristics in the parent material, MXene nanosheets. In this paper, the author provides brief insights into the properties, the existence of various types of Functional groups, and the stability of MXene quantum dots. A detailed literature review of the last five years has been provided on the energy-harvesting performance of MXene quantum dots, including their applications in solar cells, ammonia production, and CO₂ capture for valuable products. In the final section, the MQDs' challenges and future directions have been briefly addressed. MXene Quantum dots are a promising material for energy harvesting.

能源收集是一种很有前途的方法，可以最大限度地减少气候变化的影响和环境中有害气体的水平。一种具有强大能量收集特性的有前途的材料的开发使能量收集更加可行，并成为保护环境和满足世界能源需求的合适选择。MXene量子点是一种很有前途的能量收集材料，因为它们具有更高的稳定性、导电性，并且在它们的界面上存在大量的活性位点，可以为材料提供更高的反应点，从而将最大量的温室气体转化为有价值的产品，如氨、甲烷和二氧化碳。此外，MQD界面的表面官能团修饰提供了协同效益，提高了它们的收获能力。与纳米片相比，MQD的尺寸限制效应改变了它们的能量收集性能。较大的纳米片比mqd具有更少的活性位点，导致母体材料MXene纳米片的能量收集特性降低。本文简要介绍了MXene量子点的性质、各种官能团的存在性以及稳定性。对近五年来MXene量子点的能量收集性能进行了详细的文献综述，包括它们在太阳能电池、氨生产和有价值产品的二氧化碳捕获中的应用。在最后一节中，简要讨论了mqd面临的挑战和未来的方向。MXene量子点是一种很有前途的能量收集材料。

The dwindling supply of freshwater has become a dire threat to enduring prosperity and the evolution of our global community in the 21st century. Harnessing atmospheric moisture represents an auspicious strategy for addressing the water scarcity dilemma in underdeveloped regions, boasting advantages such as the deployment of rudimentary structures, autonomy from energy grids, and a minimal financial outlay. Nature-inspired materials have emerged as an auspicious innovation in water harvesting, leveraging the exceptional adaptive strategies of cacti to efficiently collect and accumulate atmospheric moisture, as well as purify water. Here, we discuss the comprehensive examination of the biomimetic characteristics of cacti that facilitate effective harvesting, utilizing their surface and morphological properties. The conical spines of cacti, renowned for their proficiency in water capture, embody an efficient model for water harvesting from the environment, as it is one of the most famous methods in dry areas. Recent advancements in materials science have enabled the synthesis of artificial materials that mimic these naturally inspired designs, including super-hydrophilic and hydrogel coatings. In this review, we categorized the significant highlights of micro/nano-structures based on their retention and absorption capabilities. Furthermore, we analyze the environmental conditions based on geographical contexts, where water scarcity is a pressing issue, and materials are effectively utilized, particularly in semi-arid and arid regions. The integration of cacti-inspired materials into existing water harvesting technologies was discussed, with an emphasis on sustainability and scalability. We aim to provide a brief overview of potential future developments to inspire the next generation of water harvesting applications.

The escalating global energy crisis and environmental challenges have accelerated the pursuit of advanced materials with precisely tunable properties. Among emerging candidates, hybrid composites integrating MXenes and metal-organic frameworks (MOFs) have garnered considerable attention owing to their synergistic functionalities and complementary advantages. MXenes are two-dimensional transition metal carbides, nitrides, or carbonitrides exhibit exceptional electrical conductivity, hydrophilicity, and mechanical robustness, while MOFs offer ultrahigh surface areas, hierarchical porosity, and structural versatility. Nevertheless, the intrinsic low conductivity and mechanical fragility of pristine MOFs hinder their broader applicability. The rational integration of MXenes with MOFs can effectively mitigates these limitations, enabling enhanced stability, charge transfer, and catalytic activity. This review systematically summarizes recent advances in the synthesis strategies, structural engineering, and physicochemical characteristics of MXenes-MOFs hybrids, with particular emphasis on their applications in catalytic CO₂ conversion to value-added chemicals. The key synthetic methodologies including etching, delamination, intercalation, and controlled MOFs assembly are critically discussed, along with persistent challenges such as achieving uniform interfacial coupling and long-term stability. Finally, the review outlines future perspectives on leveraging MXenes-MOFs composites to advance sustainable CO₂ reduction technologies and energy conversion systems.

不断升级的全球能源危机和环境挑战加速了对具有精确可调性能的先进材料的追求。在新兴的候选材料中，集成MXenes和金属有机框架（mof）的混合复合材料因其协同功能和互补优势而受到广泛关注。MXenes是二维过渡金属碳化物、氮化物或碳氮化物，具有优异的导电性、亲水性和机械稳健性，而mof具有超高表面积、分层孔隙度和结构通用性。然而，原始mof固有的低电导率和机械脆弱性阻碍了它们更广泛的应用。MXenes与mof的合理集成可以有效地缓解这些限制，增强稳定性、电荷转移和催化活性。本文系统地综述了mxenes - mof杂化材料的合成策略、结构工程和理化特性等方面的最新进展，重点介绍了mxenes - mof杂化材料在催化CO2转化为增值化学品方面的应用。关键的合成方法包括蚀刻、分层、嵌入和受控mof组装，以及实现均匀界面耦合和长期稳定性等持续挑战。最后，综述概述了利用mxenes - mof复合材料推进可持续二氧化碳减排技术和能源转换系统的未来前景。

Efficient water recovery is crucial in long-range space missions, where resupply is limited and a sufficient water supply must be provided for the entire mission duration. Water can be resupplied to the International Space Station (ISS), but for missions outside Low Earth Orbit (LEO), it is almost impossible. Even after 50 years of research, the existing Urine Processor Assembly (UPA) and Water Processor Assembly (WPA) continue to be used on the ISS for water recovery at a suboptimal rate. There is a need to improve the existing system’s efficiency, adapt it to suit the needs of long-range missions, or develop new technology. This review examines the UPA and WPA systems, highlighting their roles, efficiency, and the need for further modification. Membrane-based technologies, including Forward Osmosis (FO) and Membrane Distillation (MD), as well as emerging hybrid technologies such as integrated FO-MD and the Photocatalytic Membrane Reactor (PMR), have been discussed. Special attention has been given to brine treatment technologies, such as the Forward Osmosis Brine Dryer (FOBD), Ionomer Water Processor (IWP), Capillary Brine Residual in Containment (CapiBRIC), and Brine Evaporation Bag (BEB), which various space agencies have identified as potential alternatives. Technological advancements in developing a closed-loop biological life support system, Micro-Ecological Life Support System Alternative (MELiSSA) are also discussed. These technologies can be used as a standalone system or integrated with other treatment methods for water recycling. The review offers a critical evaluation of current water recycling systems and examines innovative technologies that can be integrated to enhance system reliability in space exploration missions.

在远程空间任务中，有效的水回收是至关重要的，因为远程空间任务的再补给是有限的，必须在整个任务期间提供足够的水供应。水可以补给到国际空间站（ISS），但对于低地球轨道（LEO）以外的任务来说，这几乎是不可能的。即使经过50年的研究，现有的尿液处理器组件（UPA）和水处理器组件（WPA）仍然在国际空间站上使用，其水回收率低于最佳水平。有必要改进现有系统的效率，使其适应远程任务的需要，或者开发新技术。本文审查了UPA和WPA系统，强调了它们的作用、效率和进一步修改的需要。膜技术，包括正向渗透（FO）和膜蒸馏（MD），以及新兴的混合技术，如集成的FO-MD和光催化膜反应器（PMR），进行了讨论。特别关注的是盐水处理技术，如正向渗透盐水干燥器（FOBD）、离子水处理器（IWP）、毛细管容器内残留盐水（CapiBRIC）和盐水蒸发袋（BEB），这些技术已被各航天机构确定为潜在的替代方案。本文还讨论了开发闭环生物生命支持系统——微生态生命支持系统替代方案（MELiSSA）的技术进展。这些技术可以作为一个独立的系统使用，也可以与其他水循环处理方法相结合。该评估对当前的水循环系统进行了批判性评估，并研究了可以集成的创新技术，以提高空间探索任务中的系统可靠性。

Red mud (RM), also known as bauxite residue, is the highly alkaline by-product generated during alumina production. Because 1–1.5 tonnes of RM can be produced per tonne of alumina and the residue is typically fine-grained and rich in Fe-Al-Si-Ti oxides, long-term storage poses risks associated with alkalinity, dusting, and trace-element leaching. This review synthesizes recent progress on RM valorization from three complementary angles: recovery of valuable resources (Fe, Al, Ti, Sc/REEs and alkali), transformation into bulk construction/functional materials (alkali-activated binders, bricks/ceramics, aggregates, and functional composites), and environmental and energy applications (adsorbents/catalysts and CO₂ mineralization). Beyond summarizing individual technologies, we highlight how feed variability (process/region), alkalinity and mineralogy govern route selection, and we compare the technology readiness, value proposition, and environmental constraints of major pathways. Finally, we propose a decision-oriented roadmap for scaling up RM utilization, emphasizing pretreatment standardization, integrated process chains, and market/regulatory alignment to enable safe, large-scale deployment.

赤泥（RM），又称铝土矿渣，是氧化铝生产过程中产生的高碱性副产品。由于每吨氧化铝可生产1-1.5吨RM，而且残渣通常颗粒细，富含Fe-Al-Si-Ti氧化物，因此长期储存会带来碱度、粉尘和微量元素浸出的风险。本文从三个互补的角度综述了稀土增值的最新进展：有价资源（铁、铝、钛、钪/稀土和碱）的回收，转化为大块建筑/功能材料（碱活化粘合剂、砖/陶瓷、骨料和功能复合材料），以及环境和能源应用（吸附剂/催化剂和CO2矿化）。除了总结单个技术之外，我们还强调了饲料可变性（工艺/地区）、碱度和矿物学如何影响路线选择，并比较了主要途径的技术准备程度、价值主张和环境约束。最后，我们提出了一个以决策为导向的路线图，用于扩大RM的利用，强调预处理标准化、集成流程链和市场/监管一致性，以实现安全的大规模部署。

The pervasive threat of arsenic (As) contamination to global health and food security demands effective remediation solutions, yet the practical application of the pioneer As-hyperaccumulator Pteris vittata is often constrained by its field performance, which is governed by a complex interplay of overlooked environmental and biological factors. To address this gap, this review systematically synthesizes the fundamental mechanisms and enhancement strategies for Pteris vittata-based phytoremediation of As. Our analysis establishes that the plant’s efficiency for As removal is not a fixed trait but an emergent property of its holobiont system. Specifically, root uptake, translocation, and vacuolar sequestration of As in plants are profoundly influenced by soil properties (e.g., pH and Eh), nutrient dynamics (e.g., phosphorus and nitrogen), climate conditions (e.g., temperature and precipitation) and crucially, the rhizosphere microbiome. We further reveal a critical physiological trade-off: microbial processes such as arsenite oxidation can mitigate phytotoxicity and promote growth, while arsenate reduction often provides a more direct pathway to enhance As accumulation. The net remediation outcome depends on the functional synergy and competition within the microbial community. In light of these, we provide a comprehensive critical assessment of advanced mitigation strategies, from the precision engineering of synthetic microbial communities to the application of omics-guided tools and machine learning for predictive modeling and optimization. By integrating plant physiology with microbiome science and data-driven analytics, this review proposes a holistic framework to transition Pteris vittata from a proven concept into a predictable, efficient, and scalable phytotechnology. This work provides an indispensable knowledge base and a clear strategic roadmap for leveraging this unique plant-microbe-environment nexus to achieve sustainable environmental restoration of As-contaminated soils and waters worldwide.

砷（As）污染对全球健康和粮食安全的普遍威胁需要有效的补救方案，但先锋As超蓄积物Pteris vittata的实际应用往往受到其现场性能的限制，这是由被忽视的环境和生物因素的复杂相互作用决定的。为了解决这一问题，本文系统地综述了蕨类植物修复砷的基本机制和增强策略。我们的分析表明，植物对砷的去除效率不是一个固定的特性，而是其全生物系统的一个新特性。具体来说，植物根系对砷的吸收、转运和液泡固存受到土壤特性（如pH和Eh）、养分动态（如磷和氮）、气候条件（如温度和降水）以及最重要的根际微生物群的深刻影响。我们进一步揭示了一个关键的生理权衡：微生物过程如亚砷酸盐氧化可以减轻植物毒性并促进生长，而砷酸盐还原通常提供了一个更直接的途径来增强砷的积累。净修复结果取决于微生物群落内部的功能协同和竞争。鉴于此，我们对先进的缓解策略进行了全面的批判性评估，从合成微生物群落的精密工程到组学指导工具和机器学习的应用，以进行预测建模和优化。通过将植物生理学与微生物组科学和数据驱动分析相结合，本文提出了一个整体框架，将vittata从一个成熟的概念转变为可预测、高效和可扩展的植物技术。这项工作为利用这种独特的植物-微生物-环境关系实现全球砷污染土壤和水的可持续环境修复提供了不可或缺的知识基础和明确的战略路线图。

Functional slow-release materials (SRMs) have emerged as a transformative approach to overcome the limitations of conventional in situ chemical oxidation (ISCO) in environmental remediation. Traditional ISCO faces challenges such as non-selective oxidant consumption, limited diffusion in low-permeability aquifers, secondary precipitation, and transient effectiveness requiring repeated injections. This review provides the first systematic comparison between KMnO₄-and persulfate (PS)-based SRMs, analyzing their distinct mechanisms, efficiencies, and environmental adaptability, and proposes a novel classification framework based on binder functionality and release kinetics. Key binder materials—including paraffin wax, gel composites, chitosan, and hydroxypropyl methyl cellulose (HPMC)—are analyzed for their roles in modulating release kinetics and enhancing pollutant degradation efficiency (e.g., 95 % trichloroethylene (TCE) removal by KMnO₄-paraffin composites, > 90 % pyrene degradation by CS-U@PS microspheres). The article further integrates diverse release kinetics models—from diffusion-controlled to empirical and multi-physics approaches—into a cohesive predictive framework for release behavior under varying hydrogeological conditions. A critical assessment of field performance demonstrates the efficacy of SRMs under diverse settings, such as 89 % TCE removal in low-permeability aquifers using optimized permanganate candles and 90.22 % PAH mineralization in high-organic soils. Future directions highlight the need for stimuli-responsive carriers, nanocomposite designs, and integrated oxidation-biodegradation systems to advance sustainable remediation.

功能缓释材料（SRMs）已成为一种革命性的方法，以克服传统的原位化学氧化（ISCO）在环境修复中的局限性。传统的ISCO面临着诸如非选择性氧化剂消耗、在低渗透含水层中扩散受限、二次沉淀以及需要反复注入的短暂有效性等挑战。本文首次对硫酸钾和过硫酸盐（PS）基SRMs进行了系统比较，分析了它们不同的机制、效率和环境适应性，并提出了一种基于粘合剂功能和释放动力学的新型分类框架。分析了主要粘结材料——包括石蜡、凝胶复合材料、壳聚糖和羟丙基甲基纤维素（HPMC）——在调节释放动力学和提高污染物降解效率方面的作用（例如，KMnO₄-石蜡复合材料去除95% %三氯乙烯（TCE）， CS-U@PS微球降解>； 90 %芘）。文章进一步整合了不同的释放动力学模型-从扩散控制到经验和多物理方法-到不同水文地质条件下释放行为的一个有凝聚力的预测框架。一项关键的现场性能评估显示了SRMs在不同环境下的有效性，例如使用优化的高锰酸盐蜡烛在低渗透含水层去除89% %的TCE，在高有机土壤中去除90.22 %的多环芳烃矿化。未来的方向强调需要刺激响应载体、纳米复合材料设计和集成的氧化-生物降解系统来推进可持续的修复。

Cyanide is regarded as one of the key prebiotic compounds potentially involved in the origin of life on Earth, but it is also a hazardous pollutant with toxic effects on human health and the environment. Before discharge, cyanide-containing wastewater must be treated to mitigate its harmful impact. This article summarizes research achievements over the past five years alongside established disposal methods. Cyanide-containing wastewater is classified into two categories based on its source: exogenous addition and endogenous generation. Subsequently, the environmental hazards and biological toxicity of cyanide-containing wastewater are evaluated. The stability of cyanide compounds and the reasons behind the difficulties in treating this wastewater are also explored. Treatment methods are categorized according to their underlying principles as physical methods, chemical oxidation methods, chemical precipitation methods, and biological treatment methods. The treatment efficacy and costs associated with these different methods are systematically compared.
