Photocatalytic technology

designed by Nanosci, proven by science.


Our technology has been developed and improved by scientists from the University of Gdańsk. See how the photocatalytic air purification process looks like.

Graphika About illustration

Nanoparticles from the photocatalyst

are irradiated with appropriate energy (e.g. titanium dioxide by UV light)


Photogenerated electrons

react with surrounding oxygen and air humidity forming reactive oxygen species, including strong hydroxyl radicals


Radicals oxidise organic compounds

such as organic pollutants, causing them to mineralize, forming carbon dioxide, water, and finally simple inorganic compounds containing heteroatoms


Nitrogen oxides (NOx)

can be converted to HNO3 or N2 respectively, while sulfur oxide (SO2) can be oxidised to sulfates


Formed both nitrates (NO3-)  sulfates(SO2-4)

can be converted to HNO3 or N2 respectively, while sulfur oxide (SO2) can be oxidised to sulfates

Our photocatalytic layers can be used in various air-purifying structures. Layers are developed and manufactured by Nanosci.

Titanium dioxide

Titanium dioxide (TiO2) nanotubes are formed directly on the carrier material (a sheet of titanium foil). Nanotubes dimensions (length, diameter, and wall thickness) can be precisely regulated by the synthesis parameters, which affect their photocatalytic activity. Shaped titanium pieces covered with TiO2 nanotubes could be easily incorporated as a photocatalytic layer in a photocatalytic engine. The manufacturing method of a thin layer of oriented TiO2 nanotubes has been patent-pending.
