Title
Mesoporous CuO/TixZr1 − xO2 catalysts for low-temperature CO oxidation
Abstract

Mesoporous CuO/TixZr1 − xO2 catalysts were prepared by a surfactant-assisted method, and characterized by N2 adsorption/desorption, TEM, XPS, in-situ FTIR and H2-TPR. The catalysts exhibited high specific surface area (SBET = 241 m2/g) and uniform pore size distribution. XPS and in-situ FTIR displayed that Cu+ and Cu2+ species coexisted in the catalysts. The CuO/TixZr1 − xO2 catalysts presented obviously higher activity in CO oxidation reaction than the CuO/TiO2 and CuO/ZrO2 catalysts. Effect of molar ratios of Ti to Zr and calcination temperature on catalytic activity was investigated. The CuO/Ti0.6Zr0.4O2 catalyst calcined at 400 °C exhibited excellent activity with 100% CO conversion at 140 °C.
