NANOCRYSTALLINE PHOTOCATALYTIC COLLOID, A METHOD OF PRODUCING IT AND ITS USE

IP Title

Summary

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

Technology Application

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
