摘要
The exploitation of efficient and stable water oxidation catalysts is a pressing challenge to solve the energy crisis. Herein, flower-like CuCo2S4 microspheres were successfully synthesized and used as an effective water oxidation catalyst. CuCo2S4/NF (NF=nickel foam) affords electrocatalytic water oxidation activity, with a current density of 20mAcm(-2) at a low overpotential of 260mV. The overpotential value is lower than that of benchmark RuO2/NF (overpotential of 340mV at a current density of 20mAcm(-2)). The water oxidation activity increases linearly before nonlinearly improving with increasing pH; this indicates that the substrate changes from water to hydroxyl. The CuCo2S4/NF catalyst is demonstrated to be a real water oxidation catalyst based on diverse experiments.
