EXAFS STUDIES ON CU ZNO/MXOY CATALYSTS FO R METHANOL SYNTHESIS/

The effect of the ternary component on the structure and catalytic beh avior of Cu/ZnO/MxOy catalysts for methanol synthesis from hydrogenati on and carbon dioxide has been studied by EXAFS. The results show that there is a relationship among the catalytic activity, the acidity of the ternary component and the dispersity of Cu respectively. It means that the active site of the catalyst of this reaction should be Cu or Cu+.
