Abstract:

It was found that under UV irradiation absorbed by titanium dioxide, in the absence of oxygen, water effectively reacts with oxygen of titanium dioxide grating. Oxygen is subsequently released into gaseous phase in the dark, thus retrieving titanium dioxide. It is supposed that the filling with oxygen of Earth’s atmosphere may take place during a similar process of reduction of oxygen-containing metal compounds of lithosphere and tropospheric solid aerosols by water under hard UV irradiation.

Keywords:
