7. Conclusion
Photocatalysis offers a number of advantages for the degradation and, in the case of well-designed systems, the mineralization of pollutants in air or water. Photocatalysis is particularly suited to low flow rates and concentrations, and can be used in conjunction with other technologies. Photocatalytic surfaces are in full development, with self-cleaning glazing and materials (concretes, cements, ceramics, tiles, paints, varnishes...) with depolluting (abatement of NO x , VOCs), disinfecting (destruction of micro-organisms), self-cleaning and anti-fogging properties.
Numerous challenges remain to improve the efficiency of photocatalytic materials. One of these concerns optimizing the efficiency and stability under visible radiation of doped titanium dioxide, which would enable better use of the solar spectrum or the...
