Abstract

Abstract

A series of bimetallic and biassistant Cu_xMn_1-xCe_0.75Zr_0.25O_y catalysts were prepared by sol-gel method. The catalytic degradation performance of toluene over the catalysts was tested in a fixed-bed reactor. The relationships between the catalytic activity of toluene degradation and catalyst structure were explored by XRD, H₂-TPR, O₂-TPD and Raman methods. It was found that the increase of copper content could enhance the interaction between Cu-Ce, and improve the oxygen vacancy concentration, lattice oxygen content and low temperature reducibility, thus promote the catalytic activity. Cu₁CeZr catalyst exhibited the best activity for toluene degradation, and the temperature of complete degradation of toluene was 220℃, which was 60℃ lower than that of Mn₁CeZr catalyst.
