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

The TiO2@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 TiO2 nanobelts. Furthermore, compared with P25, TiO2 nanobelts and PANI, the photocatalysis of TiO2@PANI nanobelts were dramatically improved. And recycling experiments confirmed that the TiO2@PANI photocatalysts had excellent stability and cycle performance. In addition, by careful investigation of influence factors, a possible mechanism was proposed.
