Mechanism for methanol synthesis on Cu-based catalyst

Abstract

Methanol synthesis reaction from CO₂ hydrogenation is carried out on Cu-based catalyst under high temperature and pressure conditions. Therefore, methanol synthesis reaction is required to develop a lower-load conversion system. The purpose of this study is to elucidate the reaction mechanism and active site in methanol synthesis reaction from CO₂ hydrogenation. The experiment was performed using in-situ FT-IR to observe the adsorbed species generated on the Cu-based powder catalyst surface. Elucidation of the reaction mechanism and the active site can provide guidelines for the design of highly active catalysts.
