A series of Cu-V-O oxide catalysts with different Cu-V molar ratios were prepared by the sol-gel method. The catalysts were characterized by means of XRD, BET and H₂-TPR. The catalytic activity and sulfur resistance for toluene combustion were tested. The results indicated that Cu₃V₂O₈ crystal structure was formed in the catalyst, which improved the lattice oxygen in the structure of Cu-doped catalysts and increased the surface area, leading to better re-dox-ability of the catalysts. The Cu_0.15V_0.85 catalyst showed the best activity and sulfur resistance. The loading of TiO₂ can significantly improve the catalytic combustion activity and sulfur resistance of the mixed oxide catalysts.
