    Abstract
  • A series of bimetallic and biassistant CuxMn1-xCe0.75Zr0.25Oy 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.
