| The
photocatalytic process or photocatalysis can be described
as follows: by adsorbing ultraviolet light quanta photocatalysts
induce chemical transformations of the substances interacting
with them.
The most essential element of the process is the oxidation
that takes place on the catalyst surface under the influence
of a mild ultraviolet light with the wavelength of less
than 300 nm (A-range). The reaction runs at a room temperature.
One of its main advantages is that no accumulation of
toxic admixtures takes place: noxious compounds decompose
into innocuous air components, such as Carbon Dioxide,
Water and Nitrogen.
Photocatalytic air purifiers are all equipped with a
special porous carrier with a TiO2 photocatalyst, which
adsorbs the light quanta and through which the air flows.
The main function of the TiO2 photocatalyst
is to adsorb organic and inorganic contaminants. Under
the influence of the A-range UV lamp they later get
decomposed into CO2 and H2O
Photocatalysis is in fact a unique opportunity to oxidize
organic compounds on mild conditions. Effective, practical
and simple to use – AIRLIFE purification systems form
your most intelligent choice.
