The hybrid Ni-P/MoSx film as efficient electrocatalyst for hydrogen evolution reaction (HER) in alkaline media has been successfully synthesized through a facile two-step electrodeposition process. The obtained hybrid Ni-P/MoSx can possess the improved activity and conductivity owing to the incorporation of Ni-P. Scanning electron microscopy (SEM) shows that the edge sites of MoSx have not been completely covered by Ni-P, exposing more active sites for HER. The better dispersion of Ni-P on the surface of MOSx has been obtained, implying the enhancement of the conductivity of Ni-P/MoSx film. The electrochemical measurements confirm that Ni-P/MoSx film has the better activity for HER than pure Ni-P and MoSx, with an overpotential of 140 mV (at j = 10 mA cm(-2)) and a low Tafel slope of 64 mV dec(-1). The improved HER activity may be attributed to the excellent conductivity of Ni-P and the synergistic effect derived from hybrid Ni-P/MoS. film. (C) 2016 Hydrogen Energy Publications LLC.
