Abstract: Cu-Mn/SiO2, impregnation catalysts were studied with respect to their catalytic activity in the synthesis of methanol.Moreover, the means of XPS, Auger, TPRand decomposition of N2Owere also used to characterize the catalysts.The experimental results show that Cu (O) mostly existed on the working surface of the catalysts.The catalytic reaction was promoted by Cu with part of positive charges which was formed by means of long path exchange function between Cu...O-Mn.Therefore, this was favourable for adsorbing and activating CO and H2 on the surface of catalysts and for promoting methanol synthesis.
Key words: Synthesis of methanol, Cu-Mn/SiO2 catalysts, Surface state of activity
