Photocatalysis is the natural phenomenon through which a substance uses light energy (natural or artificial) to clean its surface by removing contaminants and harmful compounds. Natural or artificial light encounters the TiO2 particulate in our paint and activates it, thus energizing the particle. When activated by air and light, the oxidation process begins. Organic and inorganic harmful substances that come in contact with a photocatalytic surface are broken down and transformed into harmless substances. Some of the substances that are broken down are carbon monoxide, formaldehyde, ethanol, benzene, and many more. These substances are turned into gypsum, calcium nitrate, and limestone, which are all safe substances for humans. In the case of hard surfaces, the surface becomes self-cleaning and purifies the air as polluted air passes over the surface. The treated areas are also antimicrobial, as fungal, viral and bacterial bodies cannot exist in that environment.
