Abstract

The adsorption property of CO on Fe clusters deposited on a graphite surface has been studied by temperature-programmed desorption (TPD), scanning tunneling microscopy (STM), and helium atom scattering (HAS). The desorption peak of CO is observed at ca. 330 K (or lower) independent of the amount of the deposited Fe clusters, which is much lower than those reported for single crystal surfaces of Fe. The significant reduction of the adsorption energy of CO has been ascribed to the interface interaction between Fe clusters and the graphite surface. It is also suggested that the carbonylation of Fe clusters (Fe(CO) x, x = 1-5) takes place by the multiple CO adsorption.
