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 °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 AgRh pairs.

研究了添加银和铑的二元贵金属复合氧化物对NO-CO氧化还原反应的良好作用。Ag和Rh的相互作用增强了整个复合催化剂的催化性能，在极低的150°C温度下，NO和CO的转化率达到100％。另外，由这种活性纳米颗粒组成的中孔结构导致催化剂表面上的高氧迁移率和CO反应性，显示出与催化性能的良好一致性。这种催化增强将电子云从Ag转移到Rh，这表明活性Ag Rh对之间具有良好的协同作用。
