摘要：
Tungsten carbide/carbon (WCx/C) composite was synthesized by combustion-carbothermal reduction method. Systematic experiments that vary the ratio of the carbon atom of glucose to the tungsten atom of ammonium tungstate (C/W ratio), temperature and holding time used generated to investigate the synthesis process. The morphology of the as-prepared powders is flake-like and the WCx nanoparticles are embedded in the carbon matrix. This method is facile and easy to scale up. Electrochemical measurements demonstrate that the WCx/C composite exhibits good hydrogen evolution reaction (HER) catalytic activity, giving a eta(10) (the overpotential for driving a current of 10 mA cm(-2)) of -264 mV and Tafel slope of 85 mV dec(-1) in acid solution (0.5 M H2SO4).
