Abstract Despite the intriguing potential, nano‐socketed Cu/perovskite heterostructures for CO 2 electroreduction (CO RR) are still in their infancy and rational optimization of RR properties is lacking. Here, an effective strategy reported to promote ‐to‐C 2+ conversion over by A‐site‐valence‐controlled oxygen vacancies. For proof‐of‐concept catalysts Cu/La 0.3‐x Sr 0.6+x TiO 3‐δ (x from 0 0.3), vacancy concentrations increase controllably with decreased A‐site valences (or increased x values). In flow cells, activity selectivity C present positive correlations concentrations. Among them, Cu/Sr 0.9 most vacancies shows optimal . And relative 0.3 0.6 minimum vacancies, exhibits marked improvements (up 2.4 folds) The experiments theoretical calculations suggest that optimized performance can be attributed merits provided including accelerated charge transfer, enhanced adsorption/activation reaction species, reduced energy barrier C─C coupling. Moreover, when explored a membrane‐electrode assembly electrolyzer, catalyst excellent activity, (43.9%), stability H 4 at industrial current densities, being perovskite‐based conversion.
