摘要：

The catalytic reduction of nitrogen monoxide by propene in the presence of excess oxygen over gold based ceria catalyst was studied. Adsorption and temperature programmed desorption of NO/O-2 on Au/CeO2 reveal that the catalyst adsorbs and desorbs NO over a large range of temperature. A maximum of 26% conversion of NO (x) was obtained around 210 degrees C, with a selectivity of 50% to N-2.
