| 英文摘要 | the electrocatalysts of pt/c, ptru/c and ru/c were prepared by the impregnation method. the facet characterization, the dispersion and the particle size for the catalysts were determined by means of x-ray diffraction and transmission electron microscopy. x-ray photoelectron spectroscopy was also used to analyze the state and the valency of the noble metals. the results show that the particle size was in nanometer range and the binary metals have come into being an alloy. the platinum in the catalysts existed in zero valency. the valency of the ruthenium on the surface is different from that in the body, while the ruthenium on the surface existed in oxide-form. ptru/c and pt/c are of good activity to the electrooxidation of hydrogen except ru/c. ptru/c is more tolerant of co than pt/c, and co is only adsorbed on pt. |
