The electroreduction reaction of CO2 (eCO2RR) is considered an effective pathway for clean fuel production, greenhouse gas reduction, and resource recycling. Atomically dispersed catalysts exhibit excellent catalytic activity due to the high dispersion of atoms, especially for atomically dispersed copper (AD Cu). Although copper‐based materials are considered major single component materials capable of producing multi‐carbon products, the reaction mechanism is usually not very clear. For AD Cu catalysts, the dynamic transformation of Cu species in the form of single atoms, (nano)clusters, and ions during the reaction process significantly has an effect on the performance of eCO2RR. The core issue that needs to be addressed is how to control and tune the aggregation of Cu atoms to make it most favorable for the desired product or reaction pathways. This review summarizes the optimization strategies for AD Cu in recent years from three main perspectives: interface engineering, electrode engineering, and external field coupling.

基于原子分散铜的电催化 CO2 还原优化策略：综述


CO2 的电还原反应 （eCO2RR） 被认为是清洁燃料生产、温室气体减排和资源回收的有效途径。由于原子的高分散性，原子分散催化剂表现出优异的催化活性，特别是对于原子分散铜 （AD Cu）。尽管铜基材料被认为是能够产生多碳产品的主要单组分材料，但反应机理通常不是很清楚。对于 AD Cu 催化剂，在反应过程中以单原子、（纳米）团簇和离子形式出现的 Cu 种类的动态转变对 eCO2RR 的性能有显著影响。需要解决的核心问题是如何控制和调节 Cu 原子的聚集，使其最有利于所需的产物或反应途径。本文从界面工程、电极工程和外场耦合三个主要角度总结了近年来 AD Cu 的优化策略。
