The electrochemical CO2 reduction reaction (CO2RR) to produce high value-added hydrocarbons and oxygenates presents a sustainable compelling approach toward carbon-neutral society. However, uncontrollable migration of active sites during the CO2RR limits its catalytic ability simultaneously achieve C2 selectivity ultradurability. Here, we demonstrate that generated interfacial CuAlO2 species can efficiently stabilize highly over Cu-CuAlO2-Al2O3 catalyst under harsh conditions without regeneration for long-term test. We show this unique exhibits ultradurable performance with an 85% Faradaic efficiency 300 h Such simple engineering design unveiled in work would be adaptable develop various catalysts industrial-scale CO2RR.
