摘 要：Pt-TiO2/Ce-MnOx catalysts were obtained by depositing TiO2 and platinum, respectively,on the Ce-Mn oxides prepared by co-precipitation method. The phases of CeO2 and anatase TiO2 were observed in the catalysts from X-ray diffraction （XRD） patterns. X-ray photoelectron spectroscopy （XPS） revealed that lattice oxygen and surface active oxygen were found to be the major components of O1s. The experiment results showed that the kinetic constant of thermo-photocatalysis was 7.6 times of the kinetic constant of single photocatalysis, and was 2.29 times of the kinetic constant sum of photocatalytic and thermal catalytic reaction.
