| 摘 要： | 采用溶胶-凝胶法,以偏钨酸铵为钨源,酚醛树脂(PF)为碳源制备碳化钨(WC)。使用XRD及SEM对样品进行表征,并在酸性介质中测试工作电极的电催化性能。结果表明：制备得到的纳米WC粉体颗粒径为50-90nm,颗粒形貌近似球形。WC可与Pt协同作用加强H2的电催化氧化作用,10wt%Pt/WC在0.5mol/L H2SO4 中的电流密度达12.21mA/cm2。

| Abstract: | Nano-tungsten carbide particles are synthesized by sol-gel method using ammonium metatungstate as tungsten source and phenol formaldehyde resin as carbon source. X-ray diffraction (XRD) and SEM are used to characterize the samples, and used cyclic voltammetry to test the electrochemical activity of working electrode. The results showed that the prepared nano-WC carbide particles are approximately spherical of which diameter are about 50-90 nm. WC improved hydrogen oxidation reaction by co-interacting with Pt. The current density of 10wt% Pt/WC was up to 12.21mA/cm2 in 0.5mol/L H2SO4 |
