Abstract :

Photocatalytic antibacterial studies were carried out with Escherichia coli using N and S–N co–doped anatase TiO2 catalysts in Visible light irradiation. Characterization techniques such as XRD, UV–Vis.DRS and XPS demonstrated the good dispersion properties of N and S on TiO2 prepared by sol–gel precipitation method. Comparison of relative photo catalytic efficiencies demonstrated that S–N co–doped photocatalysts exhibited higher activity in visible. More than 90% of the E–coli were deactivated within one–hour irradiation with catalyst amount 5 mg.
