| 英文摘要 | the structure and properties of pd/wo3-zro2 (w/zr=0.2) catalysts with different pd loadings and precursors were investigated. the results indicate that pd/wo3-zro2 prepared from a pdcl2 precursor was optimum for high activity and selectivity. moreover, ethylene conversion increased with the pd loading the structure and nature of the catalysts were characterized using x-ray diffraction, bet n-2 adsorption, h-2 temperature-programmed reduction and h-2 pulse adsorption techniques the results reveal that the higher catalytic performance of pd/wo3-zro2 prepared from pdcl2 could be related to the formation of polytungstate species and the existence of well-dispersed pd particles.
