Abstract

The adsorption of methanol, formaldehyde, and formic acid on Cu/ZnO and Cu/ZnO/Cr2O3 was studied by transmission infrared spectroscopy. Methanol adsorbed dissociatively to form a methoxy and hydroxyl species. Formaldehyde was adsorbed at 100°C on a zinc site through the oxygen. Adsorbed formaldehyde was very unstable at 200°C, forming methoxy and formate species. Formic acid adsorbed dissociatively to produce bidentate formate and hydroxyl species.
