摘要：

Nickel-iron (NiFe) materials with flexible structure and component have shown all-right potency for the alkaline oxygen evolution reaction (OER) due to their low reaction barriers. However, most of NiFe catalysts suffer from inferior electrocatalytic stability induced by unfavorable Fe dissolution. Herein, the selective sulfuration of FeOOH/Ni(OH)2 (NiFe) is developed to construct a reliable Fe & horbar;S interaction in FeOOH/Ni3S2/Ni(OH)2 (NiFeS) composite and subsequently restrain the Fe dissolution, realizing durable OER stability. X-ray absorption spectroscopy and theoretical calculations ...
