Abstract

Abstract: The effect of the ternary component on the structure and catalytic behavior ofCu/ZnO/M_xO_y catalysts for methanol synthesis from hydrogenation and carbon di0xide hasbeen studied by EXAFS.The results show that there is a relationship among the catalyticactivity, the acidity of the ternary component and the dispersity of Cu respectively.It meansthat the active site of the catalyst of this reaction should be Cu or Cu⁺.

Key words: EXAFS, CO₂ hydrogenation, Methanol synthesis, Cu/ZnO/M_xO_y catalyst
