REair products have been the subject of scientific experimentation in numerous research centers in order to evaluate and certify, in the various areas of application, the effectiveness and durability of the photocatalytic activity, the degree of abatement of pollutants in the outdoor environment (NOx) over time, self-cleaning benefit and the level and effectiveness of the antibacterial activity of microorganisms and non-toxicity.

Titanium Dioxide (TiO2) is classified by the US FDA (US Food and Drug Administration) as GRAS (Generally Recognized As Safe) and "Safe to use in any form" (active, inactive, micro and nano) by the European Science Commission.

Tests carried out by Studio Ambiente S.r.l. have verified the decomposition of 99.64% of the microbes of the Pseudomonas aeruginosa ATCC15442 strain present on a nickel-plated brass handle treated with a photocatalytic system based on titanium dioxide.
Other tests carried out by the Artest laboratory of Modena certify a reduction of 99.79% of the bacterial strain of Escherichia coli and 99.98% of Staphylococcus aureus. The Department of Chemistry of the University of Turin and the National Research Council show that in 60 minutes, with an irradiation at 20W m^-2, there is a 94% NOx reduction.

Numerous laboratory tests have confirmed the rapid reduction in the percentage of nicotine, benzene and formaldehyde in closed environments.

Improve air quality by using the right paints: photovoltaic paints

Ministry of the Environment / Photocatalysis is the natural phenomenon in which a substance, called a photocatalyst, through the action of light (natural or produced by special lamps) changes the speed of a chemical reaction. In the presence of air and light a strong oxidative process is activated, which leads to the decomposition of organic and inorganic substances...

Evaluation of the state of the art according to the ISO 27447: 2009 norm of the photovoltaic material REair Original

The ability of titanium oxide (TiO2) to function as a photocatalyst has been known for about 90 years [1]. A renewed interest has emerged in the last 30 years with the advent of cheap and environmentally friendly methods of TiO2 synthesis in nanometric (TiO2-NP). The nanometric size of these particles allowed to significantly increase the properties…
