Effect of calcium addition on zinc aluminate spinel

Catalysis Letters Aims and scope Submit manuscript

Abstract

The addition of calcium to zinc aluminate, prepared by coprecipitation methods, causes an increase in the specific surface area and a modification of the crystal morphology. However, the catalytic isobutane dehydrogenation properties remain unchanged. Careful characterization studies (XRD, TGA and SEM) indicate that calcium may be deposited on the zinc aluminate surface.
