Rational design of highly efficient electrocatalysts for oxygen evolution reaction (OER) is critical for sustainable energy conversion. Herein, a novel bijunction CoS/CeO2 OER electrocatalyst grown on carbon cloth is prepared through electrodeposition. Such a CoS/CeO2/CC electrocatalyst exhibits outstanding OER catalytic activity with a low overpotential of 311 mV at 10 mA•cm−2 and a low Tafel slope of 76.2 mV•dec−1. This is because the interface engineering of CoS and CeO2 facilitates charge transfer and active sites and the rich oxygen vacancies of CeO2 film promote the absorption of oxygen species in the medium.
