Abstract The CeO2 doped Cu-Co-O/Al2O3 catalyst was prepared by ultrasonic-incipient wetness impregnation method using Al2O3 as a carrier. The catalytic activity of the prepared catalyst was investigated by catalytic combustion of VOCs. XRD, H2-TPR, SEM techniques were performed to characterize the catalyst. The results showed that the dispersion of active species increased after the doping of cerium oxide. Meanwhile, the reduction temperature of Cu-Co-O catalyst reduced. The activity evaluation results showed that inlet concentration could not greatly influence the catalytic performance of the prepared catalyst. The reaction temperature of toluene and xylene combustion decreased after the doping of Cerium, especially for toluene combustion.
