摘要：

Fe deposited on TiO2(110) has been studied using AES, LEED, ISS, UPS and HREELS. The deposited Fe overlayer is found to grow in a layer-by-layer mode. Oxygen migrates from the subsurface layers of TiO2(110) to the deposited Fe during the deposition process. The chemical species of the deposited Fe depends on the state of oxidation of TiO2(110) and the amount of Fe deposition. The state of the adsorbed CO in this system is found to depend remarkably on the amount of Fe deposited on the TiO2(110) substrate. CO is found to adsorb weakly on a low Fe coverage system of 0.2 ML Fe/TiO2(110), while it is strongly chemisorbed on a high Fe coverage system of 1.7 ML Fe/TiO2(110). Difference in the CO chemisorption behavior is attributed to the different structural characteristics of these two states of the Fe/TiO2(110) system.
