Description

We investigated the oxidation of oxygen vacancies at the surface of anatase TiO2(001) using a supersonic seeded molecular beam (SSMB) of oxygen. The oxygen vacancies at the top surface and subsurface could be eliminated by the supply of oxygen using an SSMB. Oxygen vacancies are present on the surface of anatase TiO2(001) which is not performed surface cleaning prior to XPS measurements under ultra-high vacuum. These vacancies, which are stable in the ambient condition, could also be effectively eliminated by using the oxygen SSMB. (author)
