Samples of zinc oxide supported on {gamma}-Al{sub 2}O{sub 3} (5, 15, 30, and 36 Zn atoms per 100 Al atoms) have been calcined at different temperatures and subjected to oxidation-reduction treatments in order to investigate the type and the extent of the metal-support interaction and the defect state of the surface. The samples were then tested as catalysts in the decomposition of 2-propanol. They were found to give both the dehydrogenation and dehydration. The dehydrogenation reaction is due to free zinc oxide present on the surface of the support, whereas the dehydration is due to the support. The effect of the calcination temperature on the formation of a surface spinel and of the redox pretreatments on the activity and selectivity are also discussed.
