Abstract

The spatial structure and electronic structure of oxygen defect and nitrogen impurity centers of anatase and their manifestation in water adsorption, O1s XPS spectra were analyzed. The role of various forms of adsorbed water on anatase surface is considered. The results of experimental studies are compared with the properties of molecular models for the bulk and surface of titanium dioxide studied by the quantum chemical density functional theory method.
