Experimental and computational studies of nitrogen doped Degussa P25 TiO2: application to visible-light driven photo-oxidation of As(iii)

Degussa P25 TiO 2 doped with nitrogen via NH 3 treatment at 400600 C was found to be capable of catalyzing the photo-oxidation of aqueous As( iii ) to As( v ) under visible light. Substitutional doping of N for O creates NTiO surface linkages, as confirmed by XPS. Kinetic studies have been performed...
