The invention relates to a method of preparation of a titanium dioxide doped with nitrogen that involves the hydrolysis of precursor of the titanium dioxide with a first aq. ammonia solution until reaching an appreciably neutral pH, the recovery of the solid hydrolysis product, then its pretreatment by drying and calcination after at least a washing carried out with a second aq. ammonia solution. The N-containing TiO2 photocatalyst is highly reproducible with regard to its photocatalytic properties by irradiation with visible light

Abstract
The invention relates to a method of preparation of a titanium dioxide doped with nitrogen that involves the hydrolysis of precursor of the titanium dioxide with a first aq. ammonia solution until reaching an appreciably neutral pH, the recovery of the solid hydrolysis product, then its pretreatment by drying and calcination after at least a washing carried out with a second aq. ammonia solution. The N-containing TiO2 photocatalyst is highly reproducible with regard to its photocatalytic properties by irradiation with visible lightFile in questo prodotto:
