英文摘要	ru-, rh-, and pd/wo3-zro2 catalysts were studied for the direct oxidation of ethylene to acetic acid. the catalytic activity and selectivity depended strongly on the noble metals used. rh/wo3-zro2 gave the highest conversion of ethylene, whereas ru/wo3-zro2 was almost inactive. the higher catalytic activity was attributed to a better metal dispersion. pd/wo3-zro2 gave the highest selectivity for acetic acid (75%), with the selectivity of the other two catalysts being rather low (similar to 10%). temperature-programmed oxidation and h-2 reduction experiments were used to show that the strength of the noble metal-oxygen bond played an important role in product distribution. a weak metal-oxygen bond favored the formation of acetic acid, while a strong metal-oxygen bond favored the combustion of ethylene to cox.
