Nowadays, exploring the non-noble bifuntional catalysts of high efficiency activity for both HER and OER in the alkaline media attracts great interest. Herein, the CoMo2S4/MoS2 heterostructures were prepared by modified solid state method. Interestingly, the MoS2 nano sheets exhibit good matching on the surface of CoMo2S4 nano/micro rods, which would form large semicoherent interfaces. For OER, the CoMo2S4/MoS2 heterostructures exhibit higher activity than the noble metal oxides, RuO2 delivers the current density of 10 mAcm-2 at 1.52 V. Utilizing the CoMo2S4/MoS2 as the bifuntional electracatalysts for overall water splitting, it just needs 1.65 V to achieve the current density of 10 mA cm-2. It is believed that this research would attract more attention on the catalytic activity of MoS2/M-Mo2S4, in particularly, the role of semicoherent interfaces plays in the catalytic process.
