Prediction of tetraoxygen formation on rutile TiO2(110).

Abstract

In this paper, we propose a new adsorption model for molecular oxygen on reduced TiO2(110), based on extensive first principles density functional calculations. For the first time, our calculations predict formation of tetraoxygen (O4) anchored at the vacancy site, which in turn allows adsorption of three O2 molecules per vacancy in saturation coverage. We… (More)
