【 摘 要 】

tsNonprecious metal-based multicomponent nitride anchored on nanoporous high-entropy alloy skeleton is constructed for ampere-level water oxidation via in-situ configurating cooperative Brønsted basic oxyanion-solid multiple active interfaces.The self-supported nanoporous (NiFeCo)3(MoCr)3N/HEA electrodes exhibit exceptional catalytic activity and durability by virtue of MoO42− and CrO42− ions acting as molecular co-catalysts to mediate proton spillover to facilitate the formation of *OOH.The alkaline water electrolyzer assembled with nanoporous (NiFeCo)3(MoCr)3N/HEA anode and (MoCr)(NiFeCo)4/HEA cathode can operate stably at ampere-level current density for over 1700 h.
