Abstract
Catalytic properties of CuO supported on CexZr1−xO2 and WO3/CexZr1−xO2 with different Ce/Zr molar ratios are studied by using XRD, TPR, FT-IR and testing catalytic activities in low temperature CO + O2 reaction. The results show that with the addition of Zr, dispersion capacity and CO oxidation activities will decrease; H2 reduction and CO adsorption behaviors are also different. However, for copper oxide supported on CexZr1−xO2 pre-modified with WO3 full monolayer, i.e., CuO/WO3/CexZr1−xO2 samples, all these catalytic properties are similar and independent of the Ce/Zr molar ratios. Experiment results have been tentatively discussed by considering the change of surface structure of these supports.
