Beschreibung
Zusammenfassung:	Herein described are cementitious products and articles of manufacture comprising a carbon-doped titanium dioxide, having long-term photocatalytic activity. The titanium dioxide contained therein may be obtained by irradiating titanium dioxide under specific conditions of wavelength, in presence of a gas flow comprising an inert gas and an organic compound. The titanium dioxide thus treated acquires a high and stable carbon content, maintaining the specific surface area thereof substantially unaltered. The cementitious products/articles of manufacture containing it have a high and efficient photocatalytic action.
