Solid-state, surface, and catalytic properties of oxides. Progress report, October 1, 1982-August 31, 1983
Effort has been concentrated in two directions: to elucidate the relationship between surface structure and surface chemical properties, and to investigate the effect of crystallite size. Briefly, by comparing the decomposition reactions of methanol, formaldehyde, and formic acid on the nonpolar and the Zn-polar surfaces of ZnO, it was found that the Zn-polar surface was more metallic-like than the nonpolar surface. On the nonpolar surface, defects always make the surface more reactive. In the study of the crystallite size effect, it was found that the selectivity for butadiene production in the oxidative dehydrogenation of butene on iron oxide increases with decreasing crystallite size, ranging from about 40% for very large crystallites to about 80% for very small crystallites. The nonequilibrium thermodynamics of methanol synthesis from syn-gas was studied.
