A series of 1%Pd/WO 3 -ZrO 2 catalysts with different W/Zr ratios and calcination temperatures of WO 3 -ZrO 2 were prepared by an impregnation method. Their crystal structure, surface state, and acidity were determined using X-ray diffraction, N 2 adsorption, NH 3 temperature-programmed desorption,

Ru-, Rh-, and Pd/WO 3 -ZrO 2 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/WO 3 -ZrO 2 gave the highest conversion of ethylene, whereas Ru/WO 3 -ZrO 2 was almost inactive. The higher c
