A novel three-dimensional nanoporous tungsten disulfide/acetylene black (nanoporous-WS2/AB) electrocatalyst was successfully prepared by template assisted hydrothermal method and further applied to hydrogen evolution reaction (HER) for the first time. Surface morphology and crystalline structure of as-prepared nanoporous-WS2/AB were characterized by scanning electron microscopy and X-ray diffractometer. The electrocatalytic properties of as-prepared materials modified electrodes for HER were investigated by polarization curves, electrochemical impedance spectroscopy and Tafel polarization curves in 0.50 M H2SO4 solution. Compared with WS2, AB and WS2/AB based electrodes, nanoporous-WS2/AB based electrode exhibited a much higher electrocatalytic activity which was attributed to the synergistic effect between nanoflower WS2 and amorphous AB, as well as the presences of dual templates of amorphous AB and porous 4A-zeolite. The exchange current density of nanoporous-WS2/AB electrode was 1.6 and 2.5 times larger than that of WS2/AB and pure WS2 based electrode at −400 mV, respectively. The results indicated that nanoporous-WS2/AB composite would be a promising candidate for the potential application in HER.
