Hollowspherical ammoniummetatungstate (AMT), as a precursor, was prepared by an ultrasonic method. Tungsten carbide (WC) was prepared by a gas-solid reaction in an atmosphere of CO/H₂ at 700-900^oC. Microspheres were fractured by ultrasonic dispersion for 1 h. X-ray diffraction (XRD), scanning electron microscopy (SEM), thermogravimetry-differential thermal analysis (TG-DTA), Brunauer-Emmett-Teller (BET) surface area, and Barrett- Joyner-Halenda (BJH) pore-size distribution were used to characterize the morphology, mesoporous structure, and thermal stability of the sample. The results indicate that the sample is pure WC. The WC sample is stable in air at 410 ^oC and the mesopores of WC were centered at 4 nm and 22 nm. A WC powder microelectrode (WC-PME) was prepared using the prepared WC powders. The activity of WC for the electroreduction of nitrobenzene was studied by cyclic voltammetry (CV). The results indicate that the bimodal porosity of WC-PME led to higher catalytic activity than that of a Pt micro disc electrode (Pt-MDE). The reduction potential was 30 mV more positive than that of the Pt-MDE. The relation I_p-v^1/2 showed that the electrode reaction was controlled by liquid diffusion.
