Abstract

Abstract: XRD,ESR,UDRS,XPS and XAES have been used to examine the surface chemical state of Cu-Zn-Ocatalyst for methanol synthesis from carbon dioxide and hydrogen after the reduction and under the reaction conditions.The results show that only Cu⁰ on surface of the catalyst was found, no stable Cu²⁺ and Cu⁺ exist; a part of ZnO is reduced to produce lower valence Zn^(2-δ)+(0<δ<2).And Cu⁰ and Zn^(2-δ)+ is thought to be the active center of methanol synthesis reaction from carbon dioxide and hydrogen according to the activity measurement results.

Key words: CO₂+H₂, Methanol synthesis, Copper-zinc-oxygen catalyst, Active center
