Effect of surface microstructure on the photoinduced hydrophilicity of porous TiO2 thin films
TL;DR: The relationship between photoinduced hydrophilicity and surface microstructure of porous TiO2 thin films has been investigated in this article, which proves that suitable surface microstructures can enhance the photo-induced super-hydrophilic properties of porous thin films and hinder the conversion from a hydrophilic to hydrophobic state.

Photointeraction on the surface of titanium dioxide between oxygen and alkanes
TL;DR: In this article, a mechanism of the oxidation of alkanes implies the formation of an alcoholic intermediate, on primary, secondary and tertiary carbon atoms, which in turn is oxidized into aldehyde or ketone.
