摘要:A series of different catalysts were prepared by impregnation method using P25 (nano-titanium dioxide), Mt (montmorillonite) and ZSM-5 as supports, and Mn, Cu, Ce, Co and Fe as active components. The effects of catalytic oxidation were investigated to investigate the factors affecting the catalytic oxidation of toluene. The catalysts were characterized by BET, XRD and SEM. The surface morphology and pore size and pore volume were observed. It was found that MnCu0.5Ce2On/P25 had the best removal effect on toluene under the condition of 3% O2 and temperature of 240 °C. Combined with the characterization results, the pore size and pore volume are relatively large, which is beneficial to increase the selective adsorption of toluene and increase the dispersion of active components, so that the metal oxide of the active component is uniformly dispersed on the surface of the catalyst, and the catalyst is increased. The surface active site enhances the performance of catalytic oxidation of toluene.
