A Review on TiO2 in Photo Catalytic Activity and Self Cleaning Effect

Abstract

This review exemplifies the significance of TiO₂ in Photo Catalytic Activity and Self Cleaning Effect. Photo induced hydrophilicity of titanium dioxide can be used in self-cleaning. In order to comprehend the self-cleaning effect, we should first know the relation between the photo hydrophilicity and photo catalysis. The main barrier is that quick association of photo generated electron-hole pair and poor activation of TiO₂ by visible light. So to expand the activation range of TiO₂, many investigators are conducting researches by adding different kinds of dopants to TiO₂to optimize the effects.
