Pd/WO3 composite film on indium tin oxide (ITO) glass was prepared by electroplating in a solution of 50 mM tungsten-peroxo complex + 5 wt.% SDS with 5 mM PdCl2 at room temperature. The structure and composition of the synthesized Pd/WO3 composites were characterized by scanning electron microscopy combined with energy dispersion spectroscopy, X-ray photoelectron spectroscopy and X-ray diffraction. The promotional effect of WO3 for the electrocatalytic activity for hydrazine oxidation was investigated. The peak current of Pd/WO3 ITO glass electrode reached up to 106 μA, which was 1.7 times as high as that of a Pd-ITO glass electrode (62 μA) under the same working conditions. It might be mainly attributed to the good dispersion of palladium nanoparticles on WO3 supports.
