Effect of Intrinsic Properties of Anions on the Electrocatalytic Activity of NiCo₂O₄ and NiCo₂O _x S_4-x Grown by Chemical Bath Deposition.

ABSTRACT: Electrochemical water (H₂O) splitting is one of the most promising technologies for energy storage by hydrogen (H₂) generation but suffers from the requirement of high overpotential in the anodic half-reaction (oxygen evolution), which is a four-electron process. Though transition-metal oxides and oxysulfides are increasingly researched and used as oxygen evolution electrocatalysts, the bases of their differential activities are not properly understood. In this article, we have synthesized NiCo₂O₄ and NiCo₂O _x S_4-x by a chemical bath deposition technique, and the latter has shown better oxygen evolution performance, both in terms of stability and activity, under alkaline conditions.
