Photocatalysis is a natural phenomenon in which a substance, called a photoinitiator, changes the speed of a chemical reaction through the action of light. By harnessing light energy, photoinitiators induce the formation of strongly oxidising reagents that are capable of decomposing organic and inorganic substances in the atmosphere. Photocatalysis is thus an accelerator of oxidation processes that already exist in nature and thus promotes the faster decomposition of pollutants in the environment, preventing them from accumulating.

Photocatalytic activity has been applied for more than a decade to various building materials, including cementitious binders, to achieve an ‘anti-pollution’ and now an ‘anti-pollution’ effect. Worsening pollution levels in urban areas have recently emphasised interest in these materials for their ability to break down pollutants in the atmosphere. Photocatalysis thus contributes effectively to improving the quality of life.
