Abstract
0.2CuO/MgO solids prepared by impregnation method was calcined at 350 and 450 ºC. The effects of γ-rays (0.2-1.6 MGy) on its structure, surface and catalytic properties were investigated by using XRD, N2–adsorption at -196ºC and catalytic conversion of iso-propanol at 150-275 ºC using a flow technique. The results revealed that the investigated solids consisted of nano-sized MgO as a major phase beside CuO and trace amount of Cu2O. γ- Irradiation of the solids investigated exerted measurable changes on their surface and catalytic properties. These changes are dependent on the calcination temperature and dose of irradiation. The catalysts investigated acted as active dehydrogenation solids. The five yearsageing of different solids showed a limited influence on surface and catalytic properties indicating a good catalytic stability of the prepared solids.
