Electrochemical CO₂ reduction has been considered a promising approach to neutralizing the global CO₂ level. As an intriguing technique, metal-CO₂ battery devices can not only capture CO₂ into valuable carbonaceous chemicals and reduce the CO₂ concentration in the atmosphere but enable energy conversion. Among metal-CO₂ batteries, aqueous Zn–CO₂ batteries, especially rechargeable systems, exhibit flexible CO₂ electrochemistry in terms of multi-carbon chemicals, which are gaseous or water-soluble, in favor of rechargeability and cycling durability of aqueous battery systems. Despite the increasing number of publications on Zn–CO₂ batteries in the past three years, this field is still in its beginning stage and facing many challenges considering the capability of CO₂ fixation and battery performance. Herein, we present a timely and overall summary of the recent progress in Zn–CO₂ batteries, including fundamental mechanisms, affecting factors on electrochemical performance, catalyst cathodes, and electrolytes (catholytes and anolytes). Besides, we assess the application potential of Zn–CO₂ batteries and compare this with those of alkali metal-CO₂ batteries based on CO₂ fixation and battery performance. Finally, we point out some current challenges for the further development of Zn–CO₂ batteries and put forward perspectives of the research directions for practical applications of Zn–CO₂ batteries in the future.

电化学CO2还原被认为是一种很有前途的中和全球CO2水平的方法。作为一项有趣的技术，金属-二氧化碳电池装置不仅可以将二氧化碳捕获为有价值的碳质化学物质，降低大气中的二氧化碳浓度，还可以实现能量转换。在金属-CO2电池中，水性锌-CO2电池，特别是可充电系统，在气态或水溶性的多碳化学物质方面表现出灵活的CO2电化学，有利于水性电池系统的可充电性和循环耐久性。尽管近三年来关于Zn-CO2电池的文章越来越多，但考虑到CO2固定能力和电池性能，该领域仍处于起步阶段，面临许多挑战。在此，我们及时和全面地总结了锌-二氧化碳电池的最新进展，包括基本机制，电化学性能的影响因素，催化剂阴极和电解质（阴极和阳极）。此外，我们评估了锌-二氧化碳电池的应用潜力，并从二氧化碳固定和电池性能两方面对其与碱金属-二氧化碳电池进行了比较。最后，指出了当前锌- co2电池进一步发展面临的挑战，并对今后锌- co2电池实际应用的研究方向提出了展望。

Photocatalytic conversion of chemical fuels has emerged as a most challenging subject in photocatalysis which is considered as one of the sustainable solutions for environmental issues related to the energy shortage and anthropogenic carbon emissions. Herein, unique heterostructures of ZnCdS nanoplates with Bi₂S₃−terminated edges were prepared through a facile cation exchange pathway, by which the controlled photocatalytic CO₂ conversion was achieved. The optimized BZCS–NS−5 photocatalyst exhibited an excellent capacity of CO₂ photoreduction with a CO production rate of ca. 513.2 ± 5.1 μmol g⁻¹ h⁻¹ and a selectivity of ca. 91.0%, which were among the highest activities for sulfide photocatalysts documented in the literature. The outstanding photocatalytic performance was attributable to the formation of Z−scheme heterostrucutres between Bi₂S₃ and ZnCdS, in a way the separation and migration of photocarriers were accelerated. This work thus provides a feasible strategy for the construction of heterostructures to enhance the activity and selectivity of CO₂−to−CO conversion via delicate design and controlled synthesis of photocatalysts.

化学燃料的光催化转化已成为光催化领域最具挑战性的课题，被认为是解决能源短缺和人为碳排放等环境问题的可持续解决方案之一。本文通过易阳离子交换途径制备了具有Bi2S3−端部的独特异质结构的ZnCdS纳米板，实现了可控的光催化CO2转化。优化后的BZCS-NS−5光催化剂具有良好的CO2光还原能力，CO产率约为513.2±5.1 μmol g−1 h−1，选择性约为91.0%，是目前文献中活性最高的硫化光催化剂之一。由于Bi2S3与ZnCdS之间形成了Z - scheme异质结构，加速了光载流子的分离和迁移，从而获得了优异的光催化性能。因此，这项工作为构建异质结构提供了一种可行的策略，通过精心设计和控制光催化剂的合成来提高CO2 - to - CO转化的活性和选择性。

Aqueous-electrolyte-based zinc-ion batteries (ZIBs), which have significant advantages over other batteries, including low cost, high safety, high ionic conductivity, and a natural abundance of zinc, have been regarded as a potential alternative to lithium-ion batteries (LIBs). ZIBs still face some critical challenges, however, especially for building a reversible zinc anode. To address the reversibility of zinc anode, great efforts have been made on intrinsic anode engineering and anode interface modification. Less attention has been devoted to the electrolyte additives, however, which could not only significantly improve the reversibility of zinc anode, but also determine the viability and overall performance of ZIBs. This review aims to provide an overview of the two main functions of electrolyte additives, followed by details on six reasons why additives might improve the performance of ZIBs from the perspectives of creating new layers and regulating current plating/stripping processes. Furthermore, the remaining difficulties and potential directions for additives in aqueous ZIBs are also highlighted.

与其他电池相比，基于水电解质的锌离子电池（zib）具有显著的优势，包括低成本、高安全性、高离子电导率和天然丰富的锌，已被视为锂离子电池（lib）的潜在替代品。然而，ZIBs仍然面临着一些关键的挑战，特别是在构建可逆锌阳极方面。为了解决锌阳极的可逆性问题，人们在本征阳极工程和阳极界面改性方面做了大量工作。然而，电解质添加剂不仅能显著提高锌阳极的可逆性，还能决定锌阳极的活力和整体性能，这方面的研究较少。本文综述了电解质添加剂的两种主要功能，并从创建新层和调节电流电镀/剥离工艺的角度详细介绍了添加剂可能改善ZIBs性能的六个原因。此外，还指出了添加剂在水基ZIBs中存在的困难和潜在的发展方向。

The effects of seemingly inert alkali metal (AM) cations on the electrocatalytic activity of electrode materials towards reactions essential for energy provision have become the emphasis of substantial research efforts in recent years. The hydrogen and oxygen evolution reactions during alkaline water electrolysis and the oxygen electro-reduction taking place in fuel cells are of particular importance. There is no universal theory explaining all the details of the AM cation effect in electrocatalysis. For example, it remains unclear how “spectator” AM-cations can change the kinetics of electrocatalytic reactions often more significantly than the modifications of the electrode structure and composition. This situation originates partly from a lack of systematic experimental and theoretical studies of this phenomenon. The present work exploits impedance spectroscopy to investigate the influence of the AM cations on the mechanism of the hydrogen evolution reaction at Pt microelectrodes. The activity follows the trend: Li⁺≥Na⁺>K⁺>Cs⁺, where the highest activity corresponds to 0.1 M LiOH electrolytes at low overpotentials. We demonstrate that the nature of the AM cations also changes the relative contribution of the Volmer–Heyrovsky and Volmer–Tafel mechanisms to the overall reaction, with the former being more important for LiOH electrolytes. Our density functional theory-based thermodynamics and molecular dynamics calculations support these findings.

近年来，看似惰性的碱金属（AM）阳离子对电极材料的电催化活性的影响已成为大量研究工作的重点。在燃料电池中，碱水电解和氧电还原过程中的析氢和析氧反应尤为重要。没有一个通用的理论可以解释电催化中AM阳离子效应的所有细节。例如，目前尚不清楚“旁观者”am -阳离子如何比电极结构和组成的修改更显著地改变电催化反应的动力学。造成这种情况的部分原因是缺乏对这一现象的系统实验和理论研究。本文利用阻抗谱研究了AM阳离子对Pt微电极上析氢反应机理的影响。活性遵循Li+≥Na+>；K+>；Cs+的趋势，其中活性最高的对应于0.1 M的低过电位LiOH电解质。我们证明AM阳离子的性质也改变了Volmer-Heyrovsky和Volmer-Tafel机制对整个反应的相对贡献，其中前者对LiOH电解质更重要。我们基于密度泛函理论的热力学和分子动力学计算支持这些发现。

Owing to the outstanding optoelectronic properties of perovskite materials, perovskite solar cells (PSCs) have been widely studied by academic organizations and industry corporations, with great potential to become the next-generation commercial solar cells. However, critical challenges remain in preserving high efficiency practical large-scale commercialized PSCs: a) the long-term stability of the cell materials and devices, b) lead leakage, and c) methods to scale the cells for larger area applications. This paper summarizes the prior-art strategies to address the above challenges, including the latest studies on the traditional glass-glass and thin-film encapsulation methods to better improve the reliability of PSCs, new technologies for preventing lead leakage, and geometric improvement strategies to enhance the reliability, efficiency, and performance of perovskite solar modules (PSMs). Through these strategies, the device achieved enhanced performance in long-term stability tests. The encapsulation resulted in a high lead leakage inhibition rate of up to 99 %, and the PSMs possessed a geometric fill factor of 99.6 % and a power conversion efficiency (PCE) of 20.7 %. The dramatic improvement of efficiency and reliability of perovskite solar cells and modules indicate the great potential for mass production and commercialization of perovskite solar applications in the near future.

The continuous depletion of fossil fuels and the effects of climate change have encouraged prompt action to attain carbon neutrality. Technologies that transform and store renewable energy are crucial for creating a sustainable society, which is independent of fossil fuels. In this regard, electrochemical water splitting based on the oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) is an attractive technique for producing carbon-free hydrogen fuels. Additionally, rechargeable metal–air batteries (MABs) are another intriguing way for renewable energy storage through reversible oxygen reactions (OER and the oxygen reduction reaction, ORR). Herein, we comprehensively review bifunctional electrocatalysts for water splitting (HER and OER) and MABs (OER and ORR), particularly 2D carbon material-derived heterostructures. The synthesis and properties of 2D carbon materials and their energy conversion and storage mechanisms are discussed to highlight the bifunctionality of the heterostructures. Recent studies on bifunctional electrocatalysts based on 2D carbon-derived heterostructures are also reviewed. Finally, perspectives for future studies and multifunctional catalysts are presented.

In recent years, the demand for high-performance rechargeable lithium batteries has increased significantly, and many efforts have been made to boost the use of advanced electrode materials. Since graphene was first isolated by Novoselov et al., graphene/graphene-based materials have become an active area of research and are considered to be promising high-performance electrode materials. Graphene is a two-dimensional single-atom carbon-packed material that possesses fascinating properties, including a large surface area, remarkable electrical conductivity, extraordinary intrinsic electron mobility, high Young's modulus, superior mechanical strength, optical transmittance, catalytic performance, and stability. Therefore, graphene is considered an attractive material for rechargeable lithium-ion batteries (LIBs), lithium-sulfur batteries (LSBs), and lithium-oxygen batteries (LOBs). In this comprehensive review, we emphasise the recent progress in the controllable synthesis, functionalisation, and role of graphene in rechargeable lithium batteries.

In the Metal-Organic Framework (MOF) panorama, Ce(IV)-based MOFs have emerged as potential candidates for heterogeneous catalysis, not only due to their intrinsic active species but also as a support of single metal sites. As the catalytic behavior of these materials is often associated to the redox properties of cerium, a large number of spectroscopic techniques have been employed to characterize them. Unfortunately, both data acquisition and interpretation are not always straightforward and sometimes the data are not well reported and discussed, limiting their impact in the literature. In this perspective review, we critically analyse the contributions provided by different spectroscopic techniques, sometime supported by molecular modelling approaches, to unravel the nature of Ce(IV)-MOFs at any stage of their preparation and along their use (i.e., post-synthesis treatments and under reaction conditions). A concise description of major results from the recent literature allows to provide basic insights associated to the applicability and limits of most used spectroscopic approaches, showing that more robust understanding of Ce(IV)-MOFs can be achieved when a broad spectrum of techniques are used in parallel, adopting similar conditions and following good practice rules.

在金属-有机框架（MOF）的全景图中，Ce（IV）基MOF已成为多相催化的潜在候选者，不仅由于其固有的活性物质，而且由于其作为单金属位点的支持。由于这些材料的催化行为通常与铈的氧化还原性质有关，因此大量的光谱技术被用于表征它们。不幸的是，数据获取和解释并不总是直截了当的，有时数据没有得到很好的报道和讨论，限制了它们在文献中的影响。在本综述中，我们批判性地分析了不同光谱技术所提供的贡献，有时由分子模拟方法支持，以揭示Ce(IV)- mof在其制备和使用的任何阶段（即合成后处理和反应条件下）的性质。对最近文献的主要结果的简要描述可以提供与大多数使用的光谱方法的适用性和局限性相关的基本见解，表明当并行使用广泛的技术，采用类似的条件并遵循良好的实践规则时，可以实现对Ce(IV)- mof的更强大的理解。

Nitrogenous compounds (i.e., amines, amides, nitriles, oximes, amino acids and nitrogen-heterocycles derivatives) are important building blocks for synthetic chemistry, pharmaceuticals, and functional materials. Conventional synthetic strategies involve the use of toxic organic nitrogenous precursors or expensive heterogeneous catalysts under elevated temperatures and pressurized oxygen. Heterogeneous electrocatalysis can initiate the activation of inorganic N sources (i.e., NH₃ and NO_x⁻) under ambient reactions in liquid phase by applying a small bias, thus allowing the synthesis of value−added nitrogenous compounds from carbonyls, alkenes, keto acids, and even carbon dioxide in a sustainable manner without the use of oxidants/reductants. This review outlines recent developments in electrosynthesis of nitrogenous compounds using inorganic N sources, focusing on reaction mechanisms understanding, the design and optimization of efficient electrocatalysts, and the advances in cell configurations for various C‒N coupling reactions. The limitations and challenges in applications are also discussed.

含氮化合物（即胺、酰胺、腈、肟、氨基酸和氮杂环衍生物）是合成化学、药物和功能材料的重要组成部分。传统的合成策略包括在高温和加压氧下使用有毒的有机氮前体或昂贵的多相催化剂。非均相电催化可以通过施加小偏置在液相环境反应下启动无机N源（即NH3和NOx -）的活化，从而允许以可持续的方式从羰基、烯烃、酮酸甚至二氧化碳合成增值氮化合物，而无需使用氧化剂/还原剂。本文综述了无机氮源电合成含氮化合物的最新进展，重点介绍了反应机理的理解、高效电催化剂的设计和优化以及各种C-N偶联反应的电池结构的进展。讨论了应用中的局限性和挑战。
