Groping for catalysts with outstanding activity and durability is of significance toward oxygen evolution reaction (OER). We have fabricated a self-supporting electrode by decorating CeO2 on Co-Mn-S nanosheets grown on nickel foam (CeO2/Co-Mn-S/NF). As-prepared material shows preeminent electrocatalytic activity toward OER, with minor overpotential (239 mV at 10 mA cm?2) and Tafel slope (93.2 mV dec?1). Particularly, CeO2/Co-Mn-S/NF exhibits small charge transfer resistance, revealing quick Faradic process and favorable OER kinetics. Moreover, during uninterrupted water oxidation process, CeO2/Co-Mn-S/NF remains long-term stability. The strategy of decorating CeO2 on Co-Mn-S nanosheets opens a new perspective for designing highly efficient electrocatalysts toward OER.
