摘要
The copper oxide species in CuO/CeO2/Al-Zr-O catalysts showed evidently higher NO turn-over numbers for the catalytic NO reduction by CO at 300 °C than that in CuO/Al-Zr-O and CuO/γ-Al2O3 catalysts. The introduction of ceria enhanced the catalytic activity of CuO/CeO2/Al-Zr-O samples and the NO turn-over numbers of every copper atom were not influenced by the ceria loading amount. The results suggested that the Al-Zr-O mixed oxide would be a potential support for the three-way catalysts and CuO/CeO2/Al-Zr-O would be promising catalysts for the elimination of NOx.
