Abstract

The photocatalytic oxidation (PCO) can degrade a broad range of contaminants into innocuous products, with the only help of light (artificial or natural). As a consequence, photocatalytic materials, such as TiO₂, became very attractive in the development of construction materials like ceramic tiles, paving blocks, glass, paints, etc. with self-cleaning, air or water purification and antibacterial functions. The photocatalysis is proved to be effective to waste waters treatments, and to degrade gaseous pollutants such as SO_x, NO_x and volatile organic compounds (VOC). These phenomena are briefly exposed in this review, followed by a presentation of some examples of real applications.

Key words:

photocatalytic materials; titanium dioxide; atmospheric pollution; nitrogen oxides; self-cleaning materials; water decontamination
