Abstract

Catalytic decomposition of 2-propanol was studied using single crystal Zn-polar and O-polar surfaces of ZnO at an effective pressure on the surface of about 0.014 mtorr and at a temperature from 150 to 350 °C. The reaction was first order in 2-propanol. Under these conditions, the Zn-polar surface was found to be much more active than the O-polar surface. Thus the reaction is structure sensitive. The apparent activation energy was 8.8±2 kcal mol^-1 on the Zn-polar surface and 5.2±3 kcal mol^-1 on the O-polar surface. The kinetic parameters were in general agreements with those found on powder samples.
