Photo-catalysis: water or air depollution and self-cleaning materials

Atmospheric pollution, linked to ozone, motor vehicle exhaust or industrial activity to name but a few, is the cause of public health problems, odor nuisance, deterioration of the environment and buildings. The main pollutants are nitrogen oxides (NO _x ), sulfur dioxide (SO ₂ ), carbon monoxide (CO), ozone, benzene, polycyclic aromatic hydrocarbons (PAHs), other volatile organic compounds (VOCs), dust...

In this context, numerous developments have been made to develop photocatalytic coatings for NO _x...
