Studies of Catalytic CuMnO_x and Its Supported Catalyst An for Oxidation of CO

The catalyst of CuMnO_x and its supported catalyst An used for oxidation of CO were studied. The catalytic activity and crystal oxygen and amount of catalytic oxygen was examined by XRD XPS and chemical analysis. The results showed that the activity of Au-Ce/CuMnO_x is higher than that of CuMnO_x which was catalysis of Au and of Ce. By treating CuMnO_x with oxygen at 200℃, the activity of CuMnO_x varied with the quantities of its crystal oxygen. The comparasion study shows that the catalytic activity of supported An by coprecipitation is higher than that by impregnation.
