- W290659819 abstract "During the first year major effort was devoted to the building new equipment, modifying the existing equipment and training of the graduate students for the UHV analytical techniques. Meantime some experimental work was also done. The first task, the planar model catalyst development, was carried out, and a major progress has been made. Work on the oxidation of single crystal alumina has progressed to the data acquisition stage. Three planar model catalysts were developed and characterized by ESCA, AES, SEM and SIMS. The results have shown that the planar model catalysts were essentially similar to the industrial porous catalysts in oxide form. When Mo was impregnated first, majority of Co remained on the surface interacting with Mo. In this surface Co-Mo phase, the majority of Co appeared to occupy the tetrahedral sites. The geometry of the Mo species could not be determined by the techniques used. When Co was impregnated first, the majority of Co appeared to move into alumina matrix occupying tetrahedral sites in a CoAl/sub 2/O/sub 4/ type structure. The future work for the next year includes the continuation and completion of planar model catalyst, adsorption studies and continuation of a single crystal aluminum oxidation studies. 16 refs.,more » 9 figs., 5 tabs.« less" @default.
