Air purification.

air purification

The abatement of atmospheric pollution can be obtained with a natural reaction, photocatalysis, operated by a substance called photocatalyst which, activated by solar ultraviolet (UV) radiation or an artificial source, oxidizes pollutants.

Titanium dioxide (TIO2) is an excellent photocatalyst capable of degrading organic and inorganic pollutants (VOC, volatile organic compounds and NOx, nitrogen oxides) produced by human activity.

Photocatalysis transforms pollutants into salts (sodium and calcium nitrates) and carbon dioxide (C02). Salts are deposited on the ground and are removed by the simple action of wind and rain, while carbon dioxide is naturally dispersed in the atmosphere.

The compounds obtained from the degradation are soluble salts already present in the atmosphere, produced in irrelevant quantities and above all absolutely harmless for the environment and for human health.

The photoconversion of pollutants into non-hazardous substances is all the more effective the smaller the size of the titanium dioxide (Ti02) particles.

Steikos photocatalytic coatings are formulated using nanoparticle titanium oxide produced not by dispersion of powders, but by synthesis, therefore much more active and effective in the purifying action of the air.
