Photocatalytic Nanotechnology

The basic functional element of the FN® Nano coating technology is photocatalyst nanocrystals of titanium dioxide (TiO2).

Titanium dioxide nanocrystals are a semiconductor that transforms light energy into an electro-chemical force capable of effectively cleaning air, water and soil, preventing the build-up of microorganisms and ensuring self-cleaning of surfaces.

This effect is a physical reaction and it is called photocatalysis.

Photocatalytic Process

The energy of ultraviolet light of normal sunlight, is transformed into a photocatalytic effect, which only acts on the surface of the coating to a depth of approximately 9 µm. With this effect, the photocatalyst (TiO2) absorbs the light energy of ultraviolet radiation. Free electrons and electron holes appear on the surface of the photocatalyst.

The direct interaction of electrons and electron holes with molecules of the surrounding environment very effectively decomposes a wide range of organic materials, including impurities (soot, dirt, oil, particles) and odor. As a result, it also prevents the establishment and growth of microorganisms (bacteria, viruses, algae, fungi, mold).

In addition to the above-mentioned decomposition of organic pollutants, the absorption of UV radiation by the TiO2 photocatalyst also results in reactions leading to the formation of surface OH groups in the air. This leads to an increase in surface energy, which leads to a significant increase in surface hydrophilicity.

Because titanium dioxide is only involved as a catalyst in the photocatalytic reaction, it is not consumed. The effects described are therefore very long-lasting.

As a result of the photocatalytic effect, the molecules of virtually all organic substances predominantly breake down into water (H2O) and carbon dioxide (CO2). Inorganic molecules capable of oxidation are further oxidized (CO → CO2; NO → NO2; SO → SO2).

Is this technology safe?

None of the ingredients of the FN® NANO Photocatalytic coatings are toxic or cause any harm to multi-cellular organisms. All the ingredients of the coatings are natural minerals and all except titanium dioxide are necessary ingredients of the human diet. 

Pure titanium dioxide (TiO2) is a fine, white powder that is widely used in many consumer products including cosmetics, toothpaste, food coloring, pharmaceuticals, and sunscreens. TiO2 is one of the most common minerals on the planet. 

Titanium dioxide is approved by the Canadian Food Inspection Agency on the basis of Reference Listing of Accepted Construction Materials, Packaging Materials and Non-Food Chemical Products.
