Abstract
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.
Claims8
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;
