Polyaniline (PANI) is a promising conducting polymer for surface modification and sensitizing of TiO2 to achieve extended photoresponse to visible light and increased photocatalytic efficiency [1]. Reducing the level of e-/h+ recombination in TiO2 and photosensitized properties of PANI was the basis for creation of new functional PANI/TiO2 nanocomposites. Carbonization process additionally contribute improving photoactivity of TiO2 due to formation of new structures. Namely, after carbonization process of PANI component, graphene-like structures are formed [2]. On the other hand, temperature treatment during carbonization caused appearance of rutile beside anatase crystal structure of TiO2, so combination of mentioned crystal phases induced better photocatalytic activity. In this study, we report the synthesis of a carbonized PANI/TiO2composite with different initial weight ratios of PANI, which was subsequently employed for photocatalytic degradation of methylene blue (MB), Rhodamine ...B (RB) and Acid Orange 7 (AO7) under white-light irradiation. Molecular and crystal structure, morphology, and photocatalytic response of the synthesized nanocomposite were characterized by Raman spectroscopy, XRD measurements, field-emission scanning electron microscopy, and UV visible spectroscopy, respectively. Obtained results showed significant enhance of photocatalytic properties of synthesized nanocomposites in comparison to neat titania nanotubes.
