Abstract
The catalytic activity measurement for the NO+CO reaction over CuO/CeO2/gam ma -Al2O3 catalysts at a low-temperature(200 degreesC) shows that the activ ity is strongly related to ceria loading amount, and both surface dispersed ceria species and crystalline CeO2 shows a significant enhancement on the activity. The effect of ceria species is contributed to their promoting the reduction of copper oxide species.
