SiO2 – TiO2 based nanocomposite paint was developed and its use for air cleaning as well as for design of self-cleaning surfaces was successfully tested. The material exhibits also strong antibacterial effect. The coating is formed by isolated islands of titania photocatalyst surrounded with the SiO2 matrix while the SiO2 matrix is keeping units of aggregated TiO2 photocatalyst separated and can isolate the photocatalyst from direct contact with the substrate on which the material is applied. The dried composite is highly porous, thus allowing to gases to penetrate easily to the photocatalyst particles and back. The paint can be used in various aspects of environmental photocatalysis and, owing to its self-cleaning efficiency, also for improvement of appearance of various objects and monuments without changing its colour and overall appearance.
