Anchoring MoS2on an ethanol-etched Prussian blue analog for enhanced electrocatalytic efficiency for the oxygen evolution reaction

Ethanol–water etched Prussian blue analog nanocages decorated with molybdenum disulfide nanoflowers exhibit remarkable electrocatalytic activity toward the OER. The catalyst delivers an excellent OER activity with an overpotential of only 260 mV to obtain a current density of 10 mA cm −2 .
