Preparation of Polyaniline Supported TiO₂ Photocatalyst and its Photocatalytic Property

Abstract:

A polyaniline supported titanium dioxide photocatalyst was prepared by an impregnation-hydrothermal process and characterized by powder X-ray diffraction, transmission electron microscopy and UV-visible spectroscopy. It was found that the TiO₂ nanoparticles were well dispersed on the surface of the polyaniline and the photocatalyst has a stronger absorption compared with that of pure TiO₂ over the whole of the visible spectrum. The photocatalyst exhibited higher photocatalytic activity than pure TiO₂ for the photodegradation of solutions of the anthraquinone dye, reactive brilliant blue KN-R, under visible light irradiation.
