摘要：

Adsorption of carbon dioxide on potassium-covered Fe(110) at 85 K has been studied by means of UV photoelectron spectroscopy (UPS), X-ray photoelectron spectroscopy (XPS), Auger electron spectroscopy (AES) and change in work function (Delta Phi). Only a small amount of carbon dioxide dissociates into carbon monoxide and oxygen. The main reaction occurring in the studied coverage range up to one monolayer of potassium is the formation of a carbonate species and carbon monoxide. After saturation with carbonate, linear carbon dioxide is adsorbed. For potassium coverages exceeding half a monolayer, a further species could be detected with UPS. Its chemical nature is discussed and a model of the reaction paths in the investigated system is developed.
