Title
The preparation and catalytic behavior of CuO/TixSn1−xO2 catalysts for low-temperature carbon monoxide oxidation
Abstract

A series of TixSn1−xO2 (x = 1, 0.7, 0.6, 0.5, 0.3, 0) powders were synthesized by co-precipitation method and the 8 wt.% CuO/TixSn1−xO2 catalysts were prepared via deposition–precipitation method. The samples were characterized by TG-DTA, XRD, XPS and TPR techniques. The influences of the proportion of TiO2 and SnO2 and calcination temperature on the catalytic activities of the catalysts were investigated. The CuO/Ti0.6Sn0.4O2 catalyst calcined at 300 °C for 3 h showed the best catalytic performance. TPR analysis indicated that the addition of SnO2 could improve the reducibility of the catalysts. The XPS measurement showed that the copper species were mainly dispersed as Cu2+ ions.
