Promising effect of Ag/Rh paired mesoporous composite-oxide for low temperature NO-CO reaction

A promising effect of the silver and rhodium binary precious metals added composite oxide was investigated for NO-CO redox reaction. The interaction of Ag and Rh enhanced the catalytic property of the overall composite catalyst which brought to 100% conversion of NO and CO at significantly low temperature of 150 degrees C. Additionally, mesoporous structure composed of such active nano-particles leads in high oxygen mobility and CO reactivity on catalyst surface, showing a good agreement with catalytic performance. Such catalytic enhancement conveys the transfer of electronic cloud from Ag to Rh which is pointing towards good synergy between active Ag-Rh pairs.
