Self-cleaning properties of cement plates loaded with N,C-modified TiO2 photocatalysts

The photocatalytic activity of cement pastes containing nitrogen and carbon co-modified TiO2 photocatalysts (TiO2-N,C) were evaluated trough the degradation of model organic water contaminate (Reactive Red 198) under UV-vis light source. It was found that cement plates containing TiO2-N,C photocatalysts exhibited higher photocatalytic efficiency than those containing unmodified TiO2. (C) 2015 Elsevier B.V. All rights reserved.
