Solid state, surface and catalytic properties of oxides: Final report
Two areas of oxide catalysis had been studied. In the first area, the relationship between the reactivity and the surface atomic arrangement was studied using single crystal ZnO surfaces and surface science techniques. It was demonstrated for the first time that the ability of ZnO to decompose methanol depended strongly on the crystallographic orientation of the surface. Evolution of Zn atoms at temperatures much lower than the sublimation temperature was observed. In the second area, the oxide properties that affect selectivity in the oxidative dehydrogenation of hydrocarbons were investigated. The selective dehydrogenation of butene to butadiene on iron oxide was studied to understand the effect of crystallite size and crystallographic form. The dehydrogenation of alkanes was studied on various vanadate catalysts. The importance of groups and of the acidic or basic properties of the surface was investigated. Based on these and other results in the literature, a set of requirements for selective oxidation catalysts was formulated.
