Abstract: A series of Cu-Mn mixed oxide catalysts were prepared by the hydrothermal synthesis method. The catalysts were characterized by X ray diffraction, scanning electron microscope and spesific surface area. The effect of hydrothermal temperature and time, amount of precipitant on the catalytic activity for toluene combustion was investigated. The results indicate that when the hydrothermal temperature is 150 ℃ ，hydrothermal time is 24 h and the amount of substance of urea is 0.16 mol, the product Cu0.451Mn0.549O2 catalyst powders appear the uniform microcubes and lager specific surface area and show the best catalytic activity for toluene combustion. The total conversion temperature of toluene is 208 ℃.
