Heterointerface engineering of vanadium oxide/cobalt nitride as efficient electrocatalysts for alkaline overall water splitting.

Abstract

A triangular plate-shaped vanadium oxide/cobalt nitride (VO/CoN) heterostructure was constructed and used as an effective bifunctional electrocatalyst for alkaline water electrolysis. The VO/CoN-based electrolyzer exhibits a low cell voltage of 1.587 V at 10 mA cm^-2 and presents remarkable stability over 100 h of operation.
