NANOCRYSTALLINE PHOTOCATALYTIC COLLOID, A METHOD OF PRODUCING IT AND ITS USE
The present invention relates to a nanocrystalline photocatalyst active upon visible light irradiation, with a high degree of dispersion, stable in the form of a transparent colloidal solution in an aqueous environment, containing nanocrystals of titanium dioxide (TiO2) surface-modified via direct chemisorption of organic compounds. The present invention in turn relates to a method of producing the material as well as its use as a photosteriliser, photobacteriocide, photomycocide, and/or photoca
Materials based on the modified nanocrystalline titanium dioxide
can be applied as:
-self-cleaning layers, particularly suitable for transparent surfaces;
-disinfection and sterilization agents, particularly suitable for surgical instruments and other glass or plastic components used in medical applications;
-agents for microorganisms photoinactivation.
Further development of the invention is under progress at Faculty of Chemistry, Jagiellonian University. Currently the Centre for In
