Photocatalytic Decomposition of Viruses Bacteria, Fungi and Odors into Harmless Atoms and Molecules

Photocatalysis is a type of catalysis that results in the modification of the rate of a photoreaction a chemical reaction that involves the absorption of light by one or more reacting species by adding substances (catalysts) that participate in the chemical reaction without being consumed. Titanium dioxide coatings [2] (for example of FN®, FN®1 BIOMAX) are suitable for: a) long-term facade protection, b) repelling spiders, c) reducing the risk of indoor disease transmission, d) cleaning the air we breathe from allergens, pollens, bacteria, viruses, odors and molds, e) as an alternative to an air purifier, f) lasts at least 10 years on the facade and in the interior without the need for re-application One m2 of photocatalytic surface created with the help of coatings has the ability in urban and industrial agglomerations to clean the air in 60 years from 60% of harmful substances in a total volume of 3 million m3 (with an average daily exposure of 10 hours and an average wind speed of 0.2m/s)! Titanium dioxide coatings are the only sufficiently efficient and economically efficient means of significantly reducing concentrations of industrial and automotive exhaust emissions in urban and industrial agglomerations almost immediately. Titanium dioxide coatings is a highly effective nanotechnology for protection against the spread of Covid19 coronavirus infection and all other viral and bacterial infections. By painting the walls and ceiling of the room with functional coatings, you will create a highly effective protection on their surface against the deposition of pathogenic germs (viruses and bacteria), including the coronavirus Covid-19. Thanks to its microstructure, the created coating layer effectively captures viruses and airborne bacteria on its surface and subsequently eliminates them very effectively by means of photocatalysis. This also cleans the air in the room. In this way, the protection of people in the room against the transmission of viral and bacterial infections, including Covid-19, can be effectively and long-term increased. Two substances such as air and molecules of smoke or viruses and bacteria dispersed in it coexist without problems (e.g., in a smoky room). The moment the smoke particle touches an illuminated surface coated with a photocatalytic coating, it reacts with oxygen and oxidizes or burns (but the surface remains cold, it is a chemical reaction). Impurities in the air are then broken down into water and carbon dioxide molecules. Organic allergens, carcinogens, viruses, bacteria, spores, as well as decomposition of exhaust gases can be processed by photocalysis. Eventually, even the most complex organic molecules are converted into harmless simple inorganic compounds such as carbon dioxide, water and the corresponding mineral acids. Unlike various chemical preparations, the photocatalytic layer can handle microbes, because it decomposes all organic matter without distinction (Figure 1).

Equipment for photocatalytic air treatment (1)

Part of the text of the patent application: The device (1) for photocatalytic air treatment comprises a hollow body (2) provided with an air inlet (3) and an air outlet (4) and at least one photocatalytic element arranged in the hollow body (2) between the air inlet (3) and the air outlet (4). The invention consists in that the photocatalytic element is formed by at least one blade lamella (7) arranged transverse to the air flow direction, at least part of the blade lamella (7) being formed as a surface arranged helically obliquely upwards from the center of the hollow body (2) to its circumference. with respect to the air flow direction, and at least said part of the blade lamella (7) is provided with a photocatalytic layer on one side and/or on the other side, relative to the air flow direction. The vane lamella (7) may be formed by an integral helical body or several discrete vanes (5), the vane lamellae 7 forming an assembly for helical air flow.

It is certainly less dangerous to break down viruses and bacteria into harmless molecules than to be vaccinated, for example, against coronavirus. It is not known what long-term negative consequences vaccination will have on some organs of the human body. Because the covid-19 virus is constantly mutating, there may be situations where previous vaccinations will have no protection and hospital staff may also be infected. Then there will be no one who can help seriously ill patients. There would be a collapse in health care. Another big problem is that some people don’t want to be vaccinated. For such people, effective prevention is best. Therefore, the use of photocatalytic decomposition of viruses in hospitals and households, etc. is very effective as prevention. The described principle of photocatalytic air purification finds application in air conditioning units of buildings. There is no need so a large number of separate air purifiers in each room. I would like to thank UVGS GENERAL SYSTEMS ltd. for material and support in completing prototypes.
