Abstract

Abstract: The influence of adsorption and photocatalytic decomposition of organic compounds on water contact angle on TiO₂ and TiO₂ composite coated glass were investigated. The results show that the adsorption ability of TiO₂ composite film for organic compounds is weaker than that of bare glass, and it has good photocatalytic decomposition activity for the organic adsorbates. The adsorption of organic molecules on TiO₂ coated glass and bare glass is irreversible.

Key words: TiO₂ coated glass, water contact angle, antifogging, adsorption of organic compound, photocatalytic decomposition
