Abstract
Aim: To evaluate the antimicrobial properties of carbon and nitrogen doped titanium dioxide (CTiO 2 and N-TiO 2) immobilized on glass support by examining the inactivation of E. coli ATCC 25922 bacteria in water. Study Design: Sol gel synthesis was used to prepare a series of visible light responsive photocatalysts of titanium dioxide. The photo-catalysts were characterized via Fourier transform infrared spectroscopy (FT-IR), Scanning X-ray Photoelectron Spectroscopy (SXPS), X-ray Diffraction (XRD), Diffuse reflectance spectroscopy (DRS) and Energy Dispersive X-Ray Spectroscopy (EDS or EDX). Modified titanium dioxide photo-catalysts (TiO 2-SiO 2, C-TiO 2-SiO 2, and N-TiO 2-SiO 2) immobilized on glass supports were evaluated for their antimicrobial properties on the inactivation
