Characterization of dioxymethylene species over cu-zn catalysts

Dioxymethylenic species have been characterized upon adsorption of formaldehyde on zinc aluminate and copper supported on zinc aluminate, by both FTIR spectroscopy and chemical trapping. Dioxymethylene could be an intermediate in the synthesis of methanol on these catalysts in CO + H 2 and CO 2 + H...

Summary:Dioxymethylenic species have been characterized upon adsorption of formaldehyde on zinc aluminate and copper supported on zinc aluminate, by both FTIR spectroscopy and chemical trapping. Dioxymethylene could be an intermediate in the synthesis of methanol on these catalysts in CO + H 2 and CO 2 + H 2 reactions, as shown by chemical trapping experiments.
