Fe doping and oxygen vacancy modulated Fe-Ni5P4/NiFeOH nanosheets as bifunctional electrocatalysts for efficient overall water splitting

The efficient bifunctional catalysts for hydrogen and oxygen evolution reactions (HER/OER) have attracted great interest for hydrogen production from water splitting. Herein, the doping and vacancy double control strategy for the design of bifunctional catalysts is firstly demonstrated for the significant enhancement of HER/OER catalytic performances by constructing Fe doped-Ni5P4/Fe-doped Ni(OH)2 (Fe-Ni5P4/NiFeOH) hybrid nanosheets with rich...
