Although many catalysts have been reported for the CO_(2)electroreduction to C_(1)or C_(2)chemicals,the insufficient understanding of fundamental correlations among different products still hinders the development of universal catalyst design ***,we first discover that the surface*CO coverage is stable over a wide potential range and reveal a linear correlation between the partial current densities of CH_(4)and C_(2)products in this potential range,also supported by the theoretical kinetic *** on the mechanism that*CHO is the common intermediate in the formation of both CH_(4)(*CHO→CH4)and C_(1)(*CHO+*CO→C_(2)),we then unravel that this linear correlation is universal and the slope can be varied by tuning the surface*H or*CO coverage to promote the selectivity of CH_(4)or C_(2)products,*** proofs-of-concept,using carbon-coated Cu particles,the surface*H coverage can be increased to enhance CH_(4)production,presenting a high CO_(2)-to-CH_(4)Faradaic efficiency(FE_(CH_(4))~52%)and an outstanding CH_(4)partial current density of-337 m A cm;.On the other hand,using an Agdoped Cu catalyst,the CO_(2)RR selectivity is switched to the C_(2)pathway,with a substantially promoted FE;of 79%and a high partial current density of-421 m A cm;.Our discovery of tuning intermediate coverages suggests a powerful catalyst design strategy for different CO_(2)electroreduction pathways.
