Fabrication of TiO2@PANI nanobelts with the enhanced absorption and photocatalytic performance under visible light

Abstract The TiO 2 @PANI nanobelts were successfully prepared via an in-situ chemical oxidative polymerization method. The structure characterization clearly indicated that PANI could be well wedged with TiO 2 nanobelts. Furthermore, compared with P25, TiO 2 nanobelts and PANI, the photocatalysis of TiO 2 @PANI nanobelts were dramatically improved. And recycling experiments confirmed that the TiO 2 @PANI photocatalysts had excellent stability and cycle performance. In addition, by careful investigation of influence factors, a possible mechanism was proposed.
