The present disclosure relates to a rapid method of using a nanostructured zinc oxide (ZnO) catalyst for the photocatalytic degradation of a contaminant such as methyl tertiary-butyl ether (MTBE) in waste water. The degradation is carried out under a laser light wherein 100% MTBE gets degraded in a short time such as 20 minutes from the start of the irradiation.

Photocatalytic degradation of contaminant in waste water using laser light source

A zinc-based nanohybrid was prepared using a facile wet chemistry process. This nanohybrid has zinc oxide nanostructures connected to zinc phthalocyanine molecules via biologically important ligands. In addition, this nanohybrid has photocatalytic properties and photodegrades water pollutants, such as methyl orange.

The present invention relates to a novel catalyst and a process for a photo-catalytic degradation of ether-based contaminants such as methyl tertiary-butyl ether (MTBE) in water using a visible light source. The catalyst composition demonstrated complete degradation of MTBE at a room temperature in a photo-catalytic reaction conducted using a visible light source.

Method of photocatalytic degradation of contaminant in water using visible light source

This invention relates to the process of using a catalyst for the photo-catalytic degradation of methyl tertiary butyl ether (MTBE) in water. A Pd/CeO&#x2014;ZnO photo-catalyst is formed to react with MTBE dissolved in water sample and UV irradiated to reduce the MTBE concentration in the water sample. A 95-97% degradation of MTBE is observed using this process.

Process of using a catalyst for photo-catalytic degradation of contaminant in water

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.

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

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 (CeO&#x2014;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.
