Abstract The electroreduction reaction of CO 2 (eCO RR) 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 atoms, especially atomically copper (AD Cu). Although copper‐based materials are major single component capable producing multi‐carbon products, mechanism usually not very clear. For AD Cu catalysts, dynamic transformation species in form (nano)clusters, ions during process significantly has effect on performance eCO RR. core issue that needs be addressed how control tune aggregation atoms make it most favorable desired product or pathways. This review summarizes optimization strategies recent years from three main perspectives: interface engineering, electrode external field coupling.
