Ni2P-MoP2/NF纳米材料用于电催化析氢

In this paper,the phosphide composite (Ni2P-MoP2/NF) electrocatalyst was prepared by hydrothermal followed by phosphating on the substrate of high conductive NF, and its phase and morphology were characterized by XRD and SEM, at the same time, the activity of hydrogen evolution under alkaline condition was also studied. The results show that the Ni2P-MoP2/NF catalyst has been successfully prepared, and its hydrogen evolution performance is better than that of MoP2/NF because of the lower charge transfer resistance, the larger electrochemical active surface area and the synergistic effect of Mo and Ni, the overpotential of 10mA cm-2 is 96 mV. Because of the introduction of carbon cloth substrate, Ni2P-MoP2/NF was used directly as electrode during the test process, which showed excellent stability for a long time.
