摘要：

The chemisorption of carbon dioxide and its reactivity in the presence of coadsorbed water has been investigated at Al(111) surfaces through a combination of in situ X-ray and electron energy-loss spectroscopies. Carbon dioxide forms surface carbonate at low temperatures, which is readily reduced to form surface carbide and oxide. However, the particular significance of the present work is that when coadsorbed with water, there is a low-energy pathway to surface formate. The vibrational loss spectra are compared with spectra of model surface formates generated at Al(111) through interaction with formic acid and also when the latter is coadsorbed with water.
