Synthesizing and Evaluating the Photocatalytic and Antibacterial Ability of TiO₂/SiO₂ Nanocomposite for Silicate Coating.

ABSTRACT: The TiO₂/SiO₂ nanocomposite has been synthesized by a sol-gel method and investigated the effect of the SiO₂ content (0, 5, 10, 15, 20, and 50%) on the rutile-to-anatase phase transition of TiO₂ NPs. In order to increase the photocatalytic efficiency of the nanocomposite and decrease the price of material, the TiO₂/SiO₂ Nc with content SiO₂ of 15% sample is chosen for preparing silicate coating. The efficiency of photocatalytic MB and antibacterial ability in the air of W silicate coating (adding TiO₂/SiO₂ Nc (15%)) achieve almost 100% for 60 h and 94.35% for 3 h, respectively. While the efficiency of photocatalytic MB and antibacterial ability of WO silicate coating (adding commercial TiO
