Abstract

The subject of the invention is a method of making a transparent visible light activated photocatalytic superhydrophilic glass material, comprising the steps of providing a metal alcoxide with a gelating agent and a solvent, applying said solution at an heated substrate, such as window glass, borosilicate glass, soda lime glass preferably at 250°C to 450°C by ultrasonic spray, so that metal oxide layer is formed on the heated surface. The material made according to invented method is transparent (over 80%), having super hydrophilic properties (contact angle 0 deg,) and with ability to decompose volatile organic compounds (10 ppm) effectively under UV-A and ViS light, and under relative humidity at least from 6% to 40%.
