Abstract

In this study, magnetic sand and kaolin obtained from the Nigerian states of Adamawa and Bauchi, respectively, were impregnated and studied for the catalytic property of the hybrid material. The SEM micrograph showed pore structures consistent with catalyst materials. X-ray fluorescent data showed the presence of various dopant-like impurities in the sample which act to substitute some parts of essential atoms in the spinel structure, however, not forming another individual phase. X-ray diffraction analysis confirmed crystalline phases of the hybrid material being kaolinite (Al2Si2O5(OH)4), muscovite (K4Al12Si12O40) and quartz, Si3O6 minerals with an average crystallite size of 74.60 nm.
