CoNi2Se4 as an efficient bifunctional electrocatalyst for overall water splitting.

Abstract

CoNi2Se4 with a vacancy-ordered spinel structure shows excellent bifunctional electrocatalytic activity for water splitting in alkaline medium producing 10 mA cm-2 at a cell voltage of 1.61 V. For OER, an overpotential of 160 mV was needed for 10 mA cm-2 which is one of the lowest overpotentials reported to date.
