An heterogeneous conducting polymer composite, poly(3-hexylthiophene)/TiO{sub 2} (P3HT/TiO{sub 2}), was synthesized. The photocatalytic activity of P3HT alone and the composite was investigated for the first time by degrading a common dye under UV exposure. It was shown that the photocatalytic activity of the nanocomposites was higher compared to either the polymer or TiO{sub 2} alone. A simple mechanism was proposed to explain this observed synergetic effect. - Graphical abstract: Photocatalytic mechanism of the polymer composite with titania. A new heterogeneous conducting polymer composite with titania (P3HT/TiO{sub 2}) was synthesized and the photocatalytic activity this composite was investigated by degrading a common dye under UV exposure. It was shown that the nanocomposite exhibited synergetic photocatalytic catalytic activity compared to either the polymer or TiO{sub 2} alone. The scheme of the possible mechanism of enhancement of photocatalytic degradation rate in a conducting polymer nanocomposite is shown in the figure.
