Abstract
Holmia supported gamma-alumina nanocatalyst was prepared by impregnation of gamma-alumina with aqueous solution of holmium acetate hydrate Ho(CH3COO)(3)center dot 3.5 H2O. The physicochemical characteristics of the nanocatalyst calcined at 600 degrees C were established by different techniques, using surface adsorption-desorption of N-2 (S-BET), thermogravimetric analysis (TGA), X-ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM) and UV-vis diffuse reflectance spectroscopy (DRS). The recorded optical reflectance of the sample showed that the new self-assembled nanocatalyst is excellent as host material for advanced optical applications. Moreover, the catalyst showed enhanced catalytic activity toward Isopropyl alcohol decomposition.
