Abstract

Electrocatalytic CO2 reduction is one of the most promising pathways for addressing environmental and green energy concerns while converting CO2 into added value chemicals and fuels. For this purpose, single‐atom catalysts (SACs) have emerged as highly active and selective classes of materials toward electrochemical CO2 reduction (CO2RR) due to their unique electronic properties, exposed active centers, and tunable coordination environment. Herein, a critical assessment of the recent development of SACs for CO2RR is presented. Rational design and synthetic strategies of SACs have been summarized. The interaction of ligands and modulation of both activity and selectivity with extensive analysis on local atomic structure and different SAC types is discussed. The reaction mechanisms of SACs based CO2RR and synergistic effect of SACs with nanoparticles and nanoclusters are also highlighted, emphasizing enhanced catalytic performance due to improved charge transfer, optimized binding of intermediates, and improved accessibility of the active site. Finally, the future perspective of SACs based CO2RR is provided.

电化学CO2还原反应的单原子催化剂：合成策略和机理见解

电催化二氧化碳还原是解决环境和绿色能源问题的最有希望的途径之一，同时将二氧化碳转化为附加值化学品和燃料。为此，单原子催化剂（SACs）由于其独特的电子性质、暴露的活性中心和可调节的配位环境，已成为电化学CO2还原（CO2RR）的高活性和选择性材料。在此，对CO2RR的sac的最新发展进行了关键评估。总结了sac的合理设计和综合策略。本文讨论了配体的相互作用以及活性和选择性的调节，并对局部原子结构和不同SAC类型进行了广泛的分析。本文还重点介绍了基于SACs的CO2RR的反应机理以及SACs与纳米颗粒和纳米团簇的协同作用，强调了SACs通过改善电荷转移、优化中间体结合和提高活性位点的可及性来增强催化性能。最后，展望了基于sac的CO2RR技术的发展前景。
