  • Patent number: 9944540
    Abstract: 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.
    Type: Grant
    Filed: January 13, 2015
    Date of Patent: April 17, 2018
    Assignee: Umm-Al-Qura University
    Inventors: Zaki S Seddigi, Saleh Abdel-Mgeed Ahmed Saleh, Alaa A. Nassif, Mohammed M Al-Thobaiti
  • Patent number: 9403696
    Abstract: 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.

  • Patent number: 9339795
    Abstract: 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/Ce2O3—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.

  • Patent number: 9283546
    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.

  • Patent number: 9101913
    Abstract: 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 (Ce2O3—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.
