Abstract

Developing efficient electrocatalysts for the neutral oxygen evolution reaction (OER) is important but still challenging. Herein, by combining density functional theory calculations and experiments, we have demonstrated that the decoration of RuO2 can effectively accelerate the OER kinetics of Co3O4 in neutral electrolyte. High activity (365 mV at 10 mA cm-2) and decent stability (up to 100 h) are achieved by RuO2-decorated Co3O4 in 1 M PBS electrolyte.
