摘要：

We report evidence in this letter for the encapsulation of Fe clusters supported by single crystal TiO2. After thermal annealing in ultrahigh vacuum (UHV) at 500-700-degrees-C for several hours, Fe clusters are almost completely covered by Ti suboxides TiO(x) while Fe remains mainly in the metallic state. The phenomenon can be clearly measured using LEIS (low energy ion scattering) and XPS (X-ray photoelectron spectroscopy).
