Cu-Mn/γ-Al2O3 catalysts were prepared by impregnation method and calcined at different temperatures(300-600℃), which were characterized by XRD, BET, H2-TPR and XPS. Their performances for catalytic oxidation of toluene were evaluated in a fixed-bed tubular reactor, and the correlation of catalytic activity with active phases or mole ratios of both Cu+/(Cu++Cu2+) and Mn4+/(Mn4++Mn3+) was discussed. Among all catalysts, the Cu-Mn/ γ-Al2O3 catalyst calcined at 550℃ shows the best catalytic activity, with a low...
