Atmospheric NOx removal: study of cement mortars with iron- and vanadium-doped TiO2 as visible light–sensitive photocatalysts

Mortars made with Portland cement, two different calcium aluminate cements and air lime were chosen to incorporate photocatalytic additives, because they have large exposed surfaces that boost the photochemical oxidation (PCO) of atmospheric pollutants such as nitrogen oxides. TiO2 as reference cata...
