Description: Almost all photocatalytic purifiers use low pressure discharge lamps with radiation in the UV range (320 – 400 nm), which are embedded inside the hollow body directly into the middle. The main elements of photocatalytic air purifiers are porous carriers coated with a photocatalyst that is irradiated with UV light, and through which air is injected. For the practical realization of photocatalytic technologies for the disintegration of gaseous toxicants on the means of armored vehicles and stationary military structures, it is advisable to install a titanium alloy mesh in filter-absorbers of filter-ventilator installations, on the surface of which, using electrochemical technologies, a layer of titanium (IV) oxide is formed.Today’s urgent need is to determine requirements for the type of source of UV radiation that will provide uninterrupted radiation in terms of vibration, various accelerations and impacts, optimize the placement of the source of UV radiation to reduce the size and amount of “dead zones” that do not get radiation, and determine the radiation power that will ensure the energy-efficient disintegration of toxicants depending on their composition and content of air mixtures. In the purification system, titanium oxide, when absorbing a quantum of light with an energy of more than 3.2 eV (a light with a wavelength of less than 390 nm – UV), generates free charge carriers – negative electrons and positive vacancies (holes). Electrons and holes, going to the surface of TiO2, enter into redox reactions with oxygen and water or vapors of water in the air. If the compounds include nitrogen or halogen atoms X, then HNO3 and HX will be observed in the reaction products, which forces the use of activated charcoal postfilters. The only known example of a compound that cannot be oxidized by ultraviolet rays on the surface of TiO2 is carbon tetrachloride.
