Photocatalytic Antibacterial Activity of TiO₂ Thin Films by Spray Pyrolysis Technique

Abstract:

Titanium dioxide (TiO₂) thin films were deposited over glass slides by using spray pyrolysis technique to inhibit the bacteria growth. The samples were characterized by XRD, AFM methods. The XRD patterns of TiO₂ thin films showed the amorphous titanium dioxide phase (low crystallinity) and AFM images displayed the morphology of the constituted grains seems to be a fibrous microstructure. In this research, Escherichia coli (E.coli) was used as testing bacteria and the photocatalytic of TiO₂ was excited by UV light. TiO₂ thin films showed some antibacterial effect in the halo test.
