Germicide Feasibility of TiO₂/Glass Fiber and Ag-TiO₂/Glass Fiber Photocatalysts

Abstract:

Photocatalysts TiO₂ and Ag-TiO₂ supported on glass fiber were prepared by sol-gel method. Glass fibers were used not only as a substrate for TiO₂ coating to increase surface area of TiO₂ but also as an adsorbent for bacteria removal by photocatalytic reaction. The surface topography, and optical properties of materials were characterized by scanning electron microscope , and ultraviolet-visible spectroscopy. The prepared photocatalysts were applied to investigate disinfection effects of Escherichia coli (E. coli) in nursing facilities. Ag-TiO₂/glass fiber exhibits much higher photocatalytic activity for disinfection of E. coli under visible light. This increased photocatalytic activity is probably due to the Ag loading effect by narrowing the band gap of the photocatalyst and preventing the fast recombination of the photogenerated charge carriers.
