Noble metal catalysts are used for oxidation of carbon monoxide and hydrocarbons, and sincere efforts are being made worldwide to replace with non-noble metals. Conventional catalyst supports used for precious metals were not found to be suitable for base metals. The present paper investigates on the synthesis of nickel oxide supported on a non-conventional catalyst support namely, calcium phosphate-borophosphate for the oxidation of both carbon monoxide and hydrocarbons. The catalyst was synthesized with varying borate molar ratio and NiO contents. The physiochemical characterization of the catalysts was carried out using XRD, FTIR, FE-SEM and UV-Visible spectroscopic techniques which revealed the presence of required phosphate phase in the support for enhancing the oxidation process. The present catalytic system showed 83% conversion of carbon monoxide and 75% conversion of hydrocarbons.
