Title: Preparation of Cu-Co-O_x catalysts and its performance in toluene catalytic combustion
Abstract: A new Cu-Co-Ox mixed oxide catalyst, supported on self made carrier, was prepared by impregnation method and its catalytic activity for toluene combustion was examined. The effects of Cu-Co-Ox loading amount, Cu/Co molar ratio and calcining temperature on performance of the catalyst were analyzed. Crystal form and crystalline morphology of Cu-Co-Ox were characterized by X-ray diffraction (XRD), Scanning electron microscope (SEM).The experimental results showed that when the loading of Cu-Co-Ox was 5%, molar ratio of Cu/Co was 1∶2 and calcining at 600 ℃, the obtained catalyst exhibited the highest activity for toluene oxidation. Applied this Cu-Co-Ox catalyst for toluene combustion, the rate of toluene conversion could achieved 95% under the reaction temperature of 250 ℃. XRD analysis revealed that the major active material of Cu-Co-Ox was CuCo2O4.
