Abstract
Official abstract text for this publication.
This invention relates to the preparation and making use of a catalyst for the photo-catalytic degradation of methyl tertiary butyl ether (MTBE) in water. Palladium doped on composite Cerium oxide-zinc oxide (Ce 2 O 3 —ZnO) photo-catalyst was prepared by wetness incipient impregnation method. This catalyst composition demonstrated 99.6% degradation of MTBE at room temperature in a photo catalytic reaction conducted in oxygen saturated aqueous medium in the presence of UV light.
First claim
Opening claim text (preview).
What is claimed is: 1. A method, comprising: dissolving a pre-determined amount of a palladium(II)(Pd) nitrate dihydrate (Pd(NO 3 ) 2 .2H 2 O) in a deionized water to form a solution, wherein the solution is enough to cover a cerium oxide-zinc oxide particle (Ce 2 O 3 —ZnO particle); mixing Ce 2 O 3 —ZnO particle with Pd(NO 3 ) 2 .2H 2 O solution to form a Pd nitrate impregnated Ce 2 O 3 —ZnO particle; drying the Pd nitrate impregnated Ce 2 O 3 —ZnO particle; exposing the Pd…
