Recently, BiPO4has been proved to be an efficient photocatalyst which exhibits more attractive activity than that of TiO2-P25 under UV irradiation. However, photocatalytic oxidation-reduction ability of BiPO4under visible light still needs to be improved. Conjugated polymer just like polyaniline was demonstrated to be a new and efficient visible co-photocatalyst in the field of pollutant governance. As far as we know, the attempt to enhance the photochemical ability of BiPO4by employing polyaniline as a co-photocatalyst is still very limited. Hence, in order to testify the potential enhanced performance of such heterostructure, BiPO4-polyaniline heterostructure was prepared via hydrothermal method and hybridization in this paper. The experimental results indicated that several typical pollutants such as organic dyes and heavy metal ions can be effectively removed by BiPO4-polyaniline under visible light. The enhanced removal mechanism was attributed to the high separation efficiency of photo-induced electron–hole pairs and more efficient absorption of visible light after the loading of polyaniline on the surface of BiPO4as an out-layer compared with single BiPO4.

ABSTRACTThe understanding of the conformational interaction between conjugated polymers and carbon nanotubes in solution is essential to develop the applications of carbon nanotubes, particularly conjugated polymer-carbon nanotube hybrid materials. The visible absorption spectroscopic study shows that curved carbon nanotube surfaces can induce the planarization of individual conjugated polymers such as poly(p-phenyleneethynylene)s and poly(3-alkylthiophene)s in solution. The impact of nanotube surface quality on the interaction between carbon nanotubes and conjugated polymers is investigated.
