Manipulating the d-band centers of transition metal phosphides through dual metal doping towards robust overall water splitting

Abstract

By modulating the d band center via dual metal doping, and thus optimizing the adsorption free energy change for intermediates, the as prepared Ni–Mn–FeP exhibits outstanding catalytic performance toward both the OER ( η 10 = 185 mV) and HER ( η 10 = 103 mV).
