Composition of photocatalyst and method of using the same for degradation of fuel waste in contaminated water

摘要

The present disclosure relates to a novel photocatalyst composition and a process of using the photocatalyst for the photocatalytic degradation of methyl tertiary-butyl ether (MTBE) in water. Palladium doped nano zinc oxide photocatalyst was prepared by zinc nitrate hexahydrate and an ammonium carbonate and the photocatalyst composition demonstrated more than 90-99% degradation of MTBE at room temperatures in a photo catalytic reaction conducted in an oxygen saturated aqueous medium.

1. A method comprising;
mixing a zinc nitrate hexahydrate and an ammonium carbonate to obtain nano zinc oxide particles; dissolving a pre-determined amount of a palladium (II) nitrate dehydrate (Pd(NO3)2·2H2O) in deionized water comprising nano ZnO particles to form a palladium impregnated nano ZnO; drying the palladium impregnated nano ZnO overnight; exposing the palladium impregnated nano ZnO to ammonia vapors for a specific period of time; mixing and drying the palladium impregnated nano ZnO overnight; and calcining the dried palladium impregnated nano ZnO to obtain palladium doped nano zinc oxide photocatalyst.
