Synthesis and photocatalytic activity of poly(3-hexylthiophene)/TiO2 composites

摘要

An heterogeneous conducting polymer composite, poly(3-hexylthiophene)/TiO2 (P3HT/TiO2), 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 TiO2 alone. A simple mechanism was proposed to explain this observed synergetic effect. (C) 2007 Elsevier Inc. All rights reserved.
