Total Oxidation of Dichloromethane and Ethanol over Ceria-Zirconia Mixed Oxide Supported Platinum and Gold Catalysts

Original language description

Ce0.5Zr0.5O2 prepared by sol-gel method was used as a support for platinum and gold catalysts that were tested in total oxidation of dichloromethane and ethanol. It was shown that the deposition of platinum and gold on Ce0.5Zr0.5O2 support enhanced the reducibility of surface ceria which provided more oxygen available for the catalytic reaction. This phenomenon was more pronounced for platinum catalysts. Introduction of both noble metals led to the decrease of catalysts acidity. In total oxidation of dichloromethane, the noble metal catalysts showed lower catalytic performance compared to parent Ce0.5Zr0.5O2 due to lower amount of acid sites that act as chemisorption sites for chlorinated compounds. On the other hand, platinum catalysts exhibited significantly enhanced selectivity to CO2 in comparison with the Ce0.5Zr0.5O2 support. In total oxidation of ethanol, the deposition of platinum on Ce0.5Zr0.5O2 resulted in a significant increase of catalytic performance.
