Design of polymetallic sulfide NiS₂@Co₄S₃@FeS as bifunctional catalyst for high efficiency seawater splitting

Abstract

This work describes the use of NiS 2 @Co 4 S 3 @FeS as a catalyst, which provides a current density of 10 mA cm −2 with a required potential of only 1.587 V, with an emphasis on its remarkable OER selectivity for seawater splitting.
