Abstract

It is shown that the photochemical activity of titanium dioxide is significantly higher under the action of solar tropospheric radiation when it is not produced by the traditional way, but from the rutile monocrystal. The magnitudes and spectral dependences of the quantum yield of oxygen photoadsorption and carbon dioxide photodesorption for the titanium dioxide produced from a monocrystal are determined. A mechanism of a sharp increase of the titanium dioxide photoadsorption activity in the oxide surface absorption range is proposed.
