Zinc-ion hybrid supercapacitors (ZIHCs) are compelling candidates for next-generation energy storage owing to their intrinsic safety, low cost, and high power density. However, their practical implementation remains hindered by the limited energy density of traditional carbon-based cathodes. Here, we rationally design porous carbon nanofibers embedded with atomically dispersed Zn and Fe dual-metal sites (ZnFe/PCNFs), synthesized via electrospinning followed by controlled carbonization. The introduction of Fe modulates the local electronic structure of Zn centers, thereby facilitating enhanced d-orbital hybridization and stronger ion adsorption through the formation of ZnFeN6 coordination motifs. Coupled with high surface area and hierarchical porosity, these atomic-level interactions facilitate exceptional ion accessibility and rapid charge-transfer kinetics. As a cathode for ZIHCs, ZnFe/PCNFs deliver a specific capacity of 213 mAh g−1, exceptional high-rate capability, and long-term cycling stability over 20000 cycles. This work elucidates mechanisms of dual-metal atomic coordination and provides a robust design strategy for high-performance, durable aqueous energy storage systems.
锌离子混合超级电容器（zihc）因其固有的安全性、低成本和高功率密度而成为下一代储能系统的有力候选者。然而，它们的实际实施仍然受到传统碳基阴极有限的能量密度的阻碍。本研究通过静电纺丝和可控碳化的方法，合理设计了嵌入原子分散的Zn和Fe双金属位的多孔碳纳米纤维（ZnFe/PCNFs）。Fe的引入调节了Zn中心的局部电子结构，从而通过形成ZnFeN6配位基序促进了d轨道杂化和更强的离子吸附。再加上高表面积和分层孔隙度，这些原子级相互作用促进了异常的离子可及性和快速的电荷转移动力学。作为zihc的阴极，ZnFe/PCNFs提供213 mAh g- 1的比容量，卓越的高倍率能力和超过20000次循环的长期循环稳定性。这项工作阐明了双金属原子配位的机制，并为高性能、耐用的水储能系统提供了一个强大的设计策略。

Lithium metal batteries (LMBs) have attracted huge attention due to super-high capacity and low reduction potential of lithium anode constructing high-energy/power density. However, the practical application of LMBs is significantly constrained by lithium dendrite growth and high reactivity of lithium anode. Herein, a novel functionalized interlayer that SbF3 is tandem on HKUST-1 skeleton forming favorable Sb-terminated groups structure (HKSF@PE), which were proposed and fabricated to construct highly stable LMBs. Theoretical calculations demonstrate that the Sb-terminated groups structure in this configuration display strong interaction with lithium, which can act as a cation receptor and adsorption sites, thereby promoting lithium-ion desolvation and improving lithium-ion transport kinetics. Meanwhile, in-situ XRD, Raman, and DRT analyses indicate that the HKSF assist the formation of LiF-rich and lithiophilic Li3Sb alloys at SEI/Li interface, regulating lithium deposition morphology and reconstructing a reinforced SEI interlayer. Consequently, Li|HKSF@PE|Li symmetric cell exhibits exceptional stability over 2500 h at 2 mA cm−2 with 1 mAh cm−2, and Li|HKSF@PE|LFP full cell demonstrates a high-capacity retention of 92.0% after 220 cycles even at a high rate of 5C. This work reveals the important role of terminated groups to achieve homogeneous lithium deposition and provide a way to construct stable LMBs.
锂金属电池由于具有超高容量和低还原电位的锂负极构造高能/功率密度而备受关注。然而，lmb的实际应用受到锂枝晶生长和锂阳极高反应性的极大限制。本文提出并制备了一种新型功能化间层，SbF3串联在HKUST-1骨架上形成良好的sb端基结构（HKSF@PE），以构建高稳定性的lmb。理论计算表明，该构型中末端的sb基团结构与锂离子表现出较强的相互作用，可以作为阳离子受体和吸附位点，从而促进锂离子的脱溶，改善锂离子的运输动力学。同时，原位XRD、Raman和DRT分析表明，HKSF有助于在SEI/Li界面形成富liff和亲锂的Li3Sb合金，调节锂沉积形态，重建增强的SEI夹层。因此，Li|HKSF@PE|锂对称电池在2ma cm - 2和1mah cm - 2下在2500小时内表现出优异的稳定性，Li|HKSF@PE|LFP全电池在220次循环后即使在5C的高倍率下也表现出92.0%的高容量保持率。这项工作揭示了端接基团在实现均匀锂沉积中的重要作用，并为构建稳定的lmb提供了途径。

The increasing prevalence of antibiotic norfloxacin (NOR) residues in aquatic environments necessitates the research of high-efficiency and eco-friendly photocatalysts for their degradation. In this study, plasma-treated {010}-faceted BiVO4 (denoted as BiVO4-010-P) with abundant oxygen vacancies (VO) and plasmonic Bi nanoparticles was strategically employed to achieve efficient NOR degradation via peroxymonosulfate (PMS) activation. Compared with pristine BiVO4, BiVO4-010-P exhibits significantly enhanced photocatalytic PMS activation performance, achieving approximately 95% NOR removal within 80 min under white LED irradiation. Experimental and theoretical calculations prove that metallic Bi particles not only enhanced its light-absorption capacity, generating more hot electrons, but also accelerate electrons transfer from metallic Bi to BiVO4-010-VO. Meanwhile, the generation VO not only enhances PMS adsorption, but also facilitates charge transfer between BiVO4-010-VO and PMS. These synergistic effects collectively contribute to enhanced photocatalytic activity. This study proposes an innovative surface engineering strategy for designing efficient photocatalyst materials for addressing antibiotic pollutants in wastewater treatment systems.

The rational design of high-performance electrochemical energy storage devices critically depends on a fundamental understanding of ion-electrode interactions at the molecular scale. Herein, we employ interpretable machine learning (ML) to reveal electrolyte hydration energy as a universal descriptor governing ion-specific capacitance in two-dimensional (2D) materials. Through explainable ML, we elucidate how ion hydration shell stability and size critically influence charge transport and storage at the electrode-electrolyte interface. Our analysis identifies hydration energy — not ionic size — as the primary factor dictating capacitance, challenging prevailing assumptions and providing quantifiable design rules for electrolyte selection. These insights offer a data-driven pathway to optimize 2D materials for supercapacitors and beyond, including batteries and electrocatalytic systems. This work demonstrates the power of explainable artificial intelligence in uncovering molecular-level mechanisms that accelerate the discovery and development of next-generation energy storage technologies.

Oxygen vacancy (Vo) engineering has been recognized as one of the most effective strategies for enhancing the photocatalytic CO2 conversion performance of metal oxides, as it can simultaneously facilitate photogenerated charge carrier separation efficiency and provide additional surface reaction sites. However, the wide application of Vo engineering in photocatalysis are limited by its poor stability, owing to the easy recovery of these vacancy defects by atmospheric oxygen. Herein, we develop an indium (In) doping strategy to regulate the coordination environment in CeO2 with abundant Vo (CeO2-x), thereby enhance its stability during photocatalytic CO2 conversion. Confirmed by positron annihilation lifetime spectroscopy (PALS), In dopants combine with Vo by substituting for part of Ce4+, forming In3+–Vo complexes that effectively inhibit the formation of unstable vacancy clusters. Such In3+–Vo complexes can also reduce the energy required for formation of the CO products. Therefore, the optimized In-doped CeO2-x exhibits excellent photocatalytic CO2 conversion performance, with a CO yield of 301.6 μmol·g−1 after 5 h of light irradiation, and maintain high activity after four cycles of experiments. Comprehensive experimental and theoretical studies indicate that the introduction of In doping not only significantly improves the stability of Vo in CeO2-x, but also reconstruct the reaction kinetics of the CO2 conversion by forming In3+–Vo complexes thus facilitating the overall reaction.

Aqueous zinc-ion batteries (AZIBs) offer promising safety and affordability, but suffer from dendritic Zn growth and parasitic side reactions at the electrode-electrolyte interface. Herein, we construct a dual-region interfacial modulation framework by molecularly reconfiguring the Helmholtz double layer via trace methyl methacrylate (MMA). Exploiting its amphiphilic and functionally asymmetric architecture, MMA enables a coordinated interfacial reconstruction that disrupts Zn2+ solvation in the outer Helmholtz plane, builds a chemisorbed coordination layer in the inner plane, and modulates local interfacial chemistry with spatial precision. This dual-region regulation collectively suppresses water reactivity, facilitates Zn2+ desolvation, and drives crystallographically preferred deposition along the (101) plane, promoting lateral growth and mitigating dendrite formation. As a result, symmetric Zn||Zn cells exhibit over 4200 h of stable cycling at 1 mA cm−2 and maintain 1100 h of operation at 2 mA cm−2, even at 0 °C. Zn||Ti half-cells achieve a Coulombic efficiency of 99.83%, while Zn||NH4V4O10 full cells deliver 93.92% capacity retention after 400 cycles at 2 A g−1, and preserve 85.3% after 300 cycles at 0 °C. This work demonstrates a scalable, mechanism-driven electrolyte design paradigm for dendrite-free and high-performance aqueous Zn metal batteries.
水性锌离子电池（AZIBs）具有良好的安全性和可负担性，但在电极-电解质界面受到枝晶锌生长和寄生副反应的影响。在此，我们通过微量甲基丙烯酸甲酯（MMA）对亥姆霍兹双层进行分子重配置，构建了一个双区域界面调制框架。利用其两亲性和功能不对称的结构，MMA实现了协调的界面重建，破坏了外部亥姆霍兹平面上的Zn2+溶剂化，在内部平面上建立了化学吸附配位层，并以空间精度调节了局部界面化学。这种双区调控共同抑制了水反应性，促进了Zn2+的脱溶，并驱动了沿（101）平面的结晶学上的优先沉积，促进了横向生长，减轻了枝晶的形成。结果表明，对称Zn||锌电池在1ma cm - 2下可以稳定循环4200小时，在2ma cm - 2下也能保持1100小时的工作时间，即使在0°C下也是如此。Zn||Ti半电池的库仑效率为99.83%，而Zn|| nh4v4010全电池在2 a g−1下循环400次后容量保持率为93.92%，在0°C下循环300次后容量保持率为85.3%。这项工作展示了一种可扩展的、机制驱动的电解质设计范例，用于无枝晶和高性能水性锌金属电池。

Inorganic perovskite solar cells (IPSCs) offer superior thermal stability and reduced toxicity compared with hybrid perovskites, yet their practical deployment is still restricted by phase instability, interfacial degradation, and limited power conversion efficiency (PCE) under operational conditions. This review systematically outlines and connects strategies for advancing cesium lead halide (CsPbX3) systems, emphasizing three complementary directions to build a coherent narrative accessible to both experts and new readers. First, compositional tuning through halide alloying, cation substitution, and controlled doping has been shown to stabilize the black perovskite phase and suppress defect formation. Second, interfacial engineering, including surface passivation, additive-assisted nucleation, and protective layers, has emerged as a key approach to reduce non-radiative recombination and improve environmental resilience. Third, scalable fabrication routes such as solution processing, vapor deposition, and nanostructured templating are assessed for their impact on crystallinity, film uniformity, and large-area device integration. Looking ahead, future research must prioritize lead-free alternatives, low-temperature processing compatible with flexible substrates, and predictive modeling for interface optimization. By consolidating cross-disciplinary insights, this review provides a coherent roadmap to accelerate the translation of IPSCs from laboratory studies to practical, sustainable photovoltaic technologies.

Third, scalable fabrication routes such as solution processing, vapor deposition, and nanostructured templating are assessed for their impact on crystallinity, film uniformity, and large-area device integration. Looking ahead, future research must prioritize lead-free alternatives, low-temperature processing compatible with flexible substrates, and predictive modeling for interface optimization. By consolidating cross-disciplinary insights, this review provides a coherent roadmap to accelerate the translation of IPSCs from laboratory studies to practical, sustainable photovoltaic technologies.</div></div>","PeriodicalId":7283,"journal":{"name":"Advanced Powder Materials","volume":"5 2","pages":"Article 100354"},"PeriodicalIF":0.0,"publicationDate":"2025-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145570592","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The pervasive accumulation of plastic waste exacerbates environmental degradation and undermines resource circularity. Selective thermal catalysis emerges as a transformative pathway for valorizing waste plastics into value-added chemicals, yet persistent challenges in catalytic activity and product selectivity demand systematic resolution. This review decodes cutting-edge advances in thermal depolymerization by converging two critical dimensions: atomic-scale active site engineering—where rational design of coordination features and interfacial architectures regulates C–C cleavage energetics and intermediate adsorption—and macromolecular-scale manipulation of polymer transient states—leveraging nanoconfinement effects, chain folding dynamics, and thermal fragmentation to accelerate conversion kinetics. We further highlight breakthroughs in operando characterization techniques that resolve time-evolving reaction coordinates across catalytic systems. By establishing multiscale structure-activity relationships linking catalyst configurations to polymer dynamics, this analysis derives design paradigms for next-generation upcycling systems. These principles enable economically viable, industrially scalable plastic valorization while charting a strategic trajectory toward carbon-circular economies.

The demand for sustainable energy storage has accelerated the development of cellulose-based materials (CBMs) for flexible supercapacitors (FSCs). However, widespread commercialization of FSCs remains challenged by their low gravimetric energy density (approximately 35 Wh kg-1), far below lithium-ion batteries (exceeding 200 Wh kg-1), and a limited operational temperature range (from −20 °C to 60 °C), restricting their use in extreme environments. To date, no comprehensive review has elucidated the crucial role of the chemistry and structure-property relationships of CBMs in advancing FSC technology. This review fills this gap by examining the chemical attributes and versatility of cellulose and its derivatives, including their physicochemical characteristics, assembly methodologies, and functional modifications such as oxidation, esterification, etherification, grafting polymerization, nucleophilic substitution, and crosslinking reactions. We further provide an overview of the chemistry and structure-function correlations of various cellulose forms used in advanced electrodes, solid electrolytes, separators, binders, current collectors, and substrate/encapsulation materials, alongside relevant microelectrode processing technologies. Given that large-scale application of FSCs is still in its early stages, we offer insightful design principles for guiding future development of cellulose-based FSCs. By proposing a “chemistry-performance-sustainability” design framework, this review not only addresses existing limitations but also outlines a roadmap for next-generation eco-friendly FSCs.
