Title: | Visible-light-driven, dye-sensitized TiO2 photo-catalyst for self-cleaning cotton fabrics | Authors: | Ahmad, I Kan, CW |
Issue Date: | 2017 | Source: | Coatings, Nov. 2017, v. 7, no. 11, 192, p. 1-13 | Abstract: | We report here the photo-catalytic properties of dye-sensitized TiO2-coated cotton fabrics. In this study, visible-light-driven, self-cleaning cotton fabrics were developed by coating the cotton fabrics with dye-sensitized TiO2. TiO2 nano-sol was prepared via the sol-gel method and the cotton fabric was coated with this nano-sol by the dip-pad-dry-cure method. In order to enhance the photo-catalytic properties of this TiO2-coated cotton fabric under visible light irradiation, the TiO2-coated cotton fabric was dyed with a phthalocyanine-based reactive dye, C.I. Reactive Blue 25 (RB-25), as a dye sensitizer for TiO2. The photo-catalytic self-cleaning efficiency of the resulting dye/TiO2-coated cotton fabrics was evaluated by degradation of Rhodamine B (RhB) and color co-ordinate measurements. Dye/TiO2-coated cotton fabrics show very good photo-catalytic properties under visible light. | Keywords: | Self-cleaning TiO2 Visible light active photo-catalyst Dye sensitization Sol-gel method |
