Electroreduction transformation of small molecules (CO2, N2, and H2O) into chemical feedstocks offers a promising approach to eliminate carbon emissions and harness renewable energy. Most cathodic catalysts often undergo structural transformation under operating electroreduction conditions. These structural reconstructions are reflected in changes in their catalytic activity. In-depth understanding of the change of active sites and influence parameters of reconstruction behaviors is an essential precondition for the design of highly efficient catalysts. Despite the previous achievements, comprehensive insight toward the structural evolution mechanism in cathodic catalysts, compared to anode ones, under reaction conditions is still lacking. Herein, an overview of structural reconstruction for cathodic catalysts in terms of fundamental mechanisms, reconstruction process, advanced characterizations, and influencing parameters is provided. On this basis, the typical strategies for manipulating the structural reconfiguration of catalysts are also explicitly discussed from the catalyst structure and working environment. By delivering the mechanism, strategies, insights, and techniques, this review will provide a comprehensive understanding of the structural reconstruction of cathodic catalysts in electroreduction reactions and future guidelines for their rational development.

电还原反应中催化剂的结构重构：识别、理解和操作
小分子（CO 2、N 2和H 2 ）的电还原转化O) 转化为化学原料提供了一种有前途的方法来消除碳排放和利用可再生能源。大多数阴极催化剂通常在操作电还原条件下发生结构转变。这些结构重建反映在它们催化活性的变化上。深入了解活性位点的变化和重构行为的影响参数是设计高效催化剂的必要前提。尽管取得了先前的成就，但与阳极催化剂相比，在反应条件下仍然缺乏对阴极催化剂结构演变机制的全面了解。在此，从基本机制、重构过程、高级表征等方面概述了阴极催化剂的结构重构，并提供了影响参数。在此基础上，还从催化剂结构和工作环境等方面明确讨论了操纵催化剂结构重构的典型策略。通过提供机制、策略、见解和技术，这篇综述将全面了解电还原反应中阴极催化剂的结构重构及其合理开发的未来指南。
