摘      要：电化学CO_(2)还原反应(CO_(2)RR)的串联电催化策略是将CO_(2)到C_(2+)的多个步骤解耦为单独催化的CO_(2)到CO和CO到C_(2+)的两个步骤,以提高法拉第效率(FE).然而,由于CO从生成位点到反应位点的传质限制,这种策略对于C_(2+)的高速率生产仍然是挑战.本文设计了CuO/Ni单原子(SAs)串联催化剂,使得用于独立催化CO_(2)-到-CO和CO-到-C_(2+)的Ni和Cu的催化位点紧密相邻,能够原位产生和快速消耗CO.CuO/Ni SAs串联催化剂实现了高C_(2+)的部分电流密度(1220.8 mA/cm^(2)),同时仍然保持了优异的C_(2+)FE(81.4%).
