- Abstract
Traditional regulation methods of active sites have successfully optimized the performance of electrocatalysts, but seem unable to achieve further breakthrough in the catalytic activity. Unlike the conventional viewpoint of focusing on single active site, the concept of local microstructure active zone is more comprehensive and new methods to regulate the reaction zone for electrocatalytic reactions are developed accordingly. The local microstructure active zone refers to the zone with high catalytic activity formed by the interaction between active atoms and neighboring coordination atoms as well as the surrounding environment. Instead of the traditional single active atom site, the active zone is more suitable for the actual electrochemical reaction process. According to this concept, the activity of electrocatalysts can be coordinated by multiple active atoms. This strategy is beneficial for understanding the relationship between material, structure, and catalysis, which realizes the design and synthesis of high‐performance electrocatalysts. This review provides the research progress of this strategy for electrocatalytic reactions, with emphasis on their applications in oxygen evolution reaction, urea oxidation reaction, and carbon dioxide reduction.
