| 中文摘要 | The Pd/C catalysts with and without a small amount of La2O3 were synthesized by a simple reduction reaction with sodium borohydride in aqueous solution. The structure and morphology of these catalysts were characterized by X-ray diffraction, energy dispersive X-ray spectroscopy and transmission electron microscopy. The electrocatalytic performance of these catalysts for methanol oxidation in alkaline media was investigated using cyclic voltammetry, chronoamperometry and CO stripping experiments. The results show that the Pd La2O3/C catalyst has a higher catalytic activity than the Pd/C catalyst, but the effect of La2O3 cannot be explained by a bi-functional mechanism. X-Ray photoelectron spectroscopy analyses suggest that the higher content of metallic Pd caused by the addition of La2O3 contributes to the better catalytic activity of Pd La2O3/C. Based on the good electrocatalytic performance of Pd La2O3/C, the Pd La2O3 catalyst supported on chitosan (CS)-functionalized activated carbon nanotubes was prepared, and it exhibited a better catalytic activity. The improvement is attributed to the good dispersion status of metal particles and the further increase of metallic Pd due to the presence of CS.
