“…S6). Two bands were also observed at 1042 cm −1 and 1172 cm −1 that were attributed to the stretching vibrations of O O bonds coordinated [67]. These peaks were not observed in the case of the fabrics without TiO 2 and confirm the formation of bidentate carboxylic ligand.…”

a b s t r a c tThe purpose of this work is to obtain photocatalytic fabrics based on reduced graphene oxide (RGO) and TiO 2 coatings on polyester fabrics. The influence of the applied number of RGO coatings on properties such as light absorption, conductivity, electroactivity and photocatalytic properties of the fabrics was established. An improvement of these properties with the number of RGO coatings applied was obtained. FESEM, EDX, XPS and FTIR-ATR showed the incorporation of the TiO 2 nanoparticles on the fabrics. FTIR-ATR showed the formation of a bidentate carboxylic ligand with titanium atoms. The photocatalytic properties of the fabrics were tested with Rhodamine B dye solutions. Photocatalytic efficiency increased with the number of RGO coatings, due to the increased light absorption, and better electrical properties. The charge transfer resistance (R ct ) and its time constant ( ) decreased, indicating a better electron transfer which helps to increase the lifetime of the pair electron/hole.
