Pt/rh and pd/rh catalysts used for ozone decomposition and simultaneous elimination of ozone and carbon monoxide

摘要

Catalytic oxidation of CO in the gas phase with ozone was carried out at lower temperature.The catalytic activities of Pt/Rh and Pd/Rh monolith honeycomb catalysts for the catalytic thermal oxidation and catalytic ozone oxidation were compared.Thermal catalytic combustion is a typical catalytic oxidation technique in industry.Catalysts can change reaction pathways at lower activation energy than gas phase combustion and thus allows oxidation to proceed at a lower temperature.Noble metals such as palladium and platinum are well-known highly active catalysts for the full oxidation of carbon monoxide,methane and olefins [1].They are also key components of the three-way converters used in the treatment of automobile exhaust [2,3].
