Abstract: The catalytic activity measurement for the NO+COreaction over CuO/CeO2/γ-Al2O3 catalysts at a low-temperature(200 ℃) shows that the activity 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.

Key words: CuO, CeO2, γ-Al2O3
