The electrocatalytic reduction of CO2 (CO2RR) to high-value chemicals and fuels offers a promising route for clean carbon cycle. However, it often suffers from low catalytic activity poor selectivity. Heterostructure construction has been shown be an effective strategy producing multi-carbon products, but the synergistic mechanisms between multiple active sites resulting reconstruction process remain unclear. In this study, Ga2O3/CuO heterostructure is established via simple sol-gel method produce C2+ products. Experimental results demonstrate that Ga2O3 stabilizes Cu+ form Cu0/Cu+/Ga centers enhances water-splitting ability during reaction. improved hydrogen absorption on Ga site shifts C─C coupling reaction pathway *OCCO asymmetric *OCCHO path with lower energy barrier. As result, catalysts exhibit superior CO2RR performance, achieving 70.1% Faradaic efficiency at -1.2 VRHE in flow cell, ethylene reaching 58.3% remaining stable 10 h.
