Preparation and properties of Ag−TiO₂ thin films on glass substrates

Abstract

Ag−TiO₂ thin films were prepared on glasses. The morphology and structure of Ag−TiO₂ films were investigated by XRD, SEM and FT-IR. The photocatalytic and hydrophilic properties of Ag−TiO₂ thin films were also evaluated by examining photocatalytic degradation dichlorophos under sunlight illumination and the change of contact angle respectively. The research results show that the Ag−TiO₂ thin film is mainly composed of 20–100 nm Ag and TiO₂ particles. The Ag−TiO₂ thin films possess a super-hydrophilic ability and higher photocatalytic activity than that of pure TiO₂ thin film.
