Visible lightsensitive photocatalytic aditives to CORE
TiO2 has been incorporated to cementbased materials to obtain depollutant and selfcleaning building materials. With the aim of broadening the sensitivity of these materials towards the visible light, two doped photocatalytic additives based on TiO2 were synthesized and used. Flame spray pyrolysis (FSP) allowed us to obtain TiO2 doped with either Fe or V, which generated holeelectron pairs
