摘要: The conducted studies were focused on the development of gypsum material exhibiting self-cleaning properties. To this end, raw was mixed with unique TiO2-based photocatalysts, previously modifi ed by nitrogen and/ or carbon doping. photocatalytic activity obtained plasters evaluated trough degradation model organic compound (Reactive Red 198) under UV-vis irradiation. impact photocatalysts presence physicochemical properties evaluated. Furthermore, role non-metals TiO2 determined. It confi rmed that addition N,C co-modifi titanium dioxide into bestows highest dye removal rate displayed plaster containing optimal amount (10 wt%) TiO2/N,C photocatalyst, after 20 hours
