Preparation of nano-TiO₂ by liquid hydrolysis and characterization of its antibacterial activity

Abstract

The nano-TiO₂ particles were prepared by liquid hydrolysis method and characterized using XRD. Its antibacterial activity against two representative bacterial, Escherichia coli and Staphylococcus aureus, was also studied. The experimental results showed that the nano-TiO₂ calcinated at 600–700 °C contained the obvious anatase phase and exerted excellent antibacterial activity. The feature of antibacterial activity of nano-TiO₂ was non-strains specificity and exerted best antibacterial activity at concentration of 0.8 g/L.

Keywords
