摘要：

A number of probe reactions including hydrogenation, hydrogenolysis, exchange and oxidation have been investigated over two series of Pt/SiO//2 and Pt/Al//2O//3 catalysts. These encompass a wide range of percentage metal exposed, and have been thoroughly characterized by hydrogen chemisorption, reactivity of surface oxygen and x-ray line profile analysis. While the original interest was to examine the relation between metal morphology and catalytic behavior, it turns out that pretreatment conditions are as important, or more so, in the determination of catalytic activity and selectivity.
