| 英文摘要 | vulcan xc-72rcarbon supported pd nanoparticles was obtained in a nh3-mediated polyol process without any protective agent and characterized by x-ray diffraction (xrd) and transmission electron microscope (tem) techniques. the added nh3 species is found to have a strong complex ability to pd, which not only avoids the formation of pd hydroxide precipitate resulted from pd hydrolysis, but also restrains the further complete reduction of pd. temperature-programmed reduction equipped with a mass spectrometry (tpr-ms) is employed to study the reductive behavior of unreduced pd complex in pd/c catalyst and the results show that the post-treatment in a reductive atmosphere at higher temperature is needed to ensure the complete reduction of pd. xrd patterns show the heat-treated pd/c sample in a reductive atmosphere has a face centered cubic crystal structure and tem image indicates that the dispersion of pd nanoparticles on the carbon support is uniform and in a narrow particle size range. thermodynamic data analysis is carried out to elucidate the possible reaction pathway for the preparation of pd/c catalyst in this process. the obtained pd/c catalyst shows high activity to formic acid oxidation and high selectivity to oxygen reduction reaction (orr) with the presence of methanol.
