摘要： The electrochemical hydrogen evolution reaction (HER) on a non-precious electrocatalyst in an alkaline environment is of essential importance for future renewable energy. The design of advanced electrocatalysts for HER is the most important part to reduce the cost and to enhance the efficiency of water splitting. MoS2 is considered as one of the most promising electrocatalysts to replace the precious Pt catalyst. Herein, for the first time, we have successfully loaded MoS2 electrocatalysts onto the Co3O4 nanosheet array to catalyze HER with a low onset potential of ~76 mV. The high hydrogen evolution activity of MoS2 supported on the Co3O4 nanosheet array may be attributed to the increased active sites and the electronic interactions between MoS2 and Co3O4.
