Abstract

In the methanol synthesis by CO2 hydrogenation on the Cu catalyst, in order to observe the hydrogenation process after formate(HCOO) and unstable intermediates, formate is adsorbed on the Cu(111) model surface and is hydrogenated by the atomic hydrogen at low temperature. Formate reversibly adopted bidentate and monodentate structures, and a chemical species considered to be dioxymethylene and formaldehyde were observed.
