Investigation of Photocatalytic Activity of TiO₂-PANi Nanocomposites

Abstract:

In this paper the photocatalytic activity of TiO₂-PANi nanocomposites prepared using two different In-situ polymerization methods have been investigated. The same pressure, temperature, precursors, mole ratio, and solvent have been employed for preparation of nanocomposites. The synthesized nanocomposites were characterized by FESEM, XRD and FTIR. Results revealed the successful preparation of TiO₂- PANI nanocomposites. TiO₂-PANi nanocomposite synthesized using method 2 showed very well dispersed TiO₂ nanoparticles on the surface of PANi. There is no agglomeration of TiO₂ nanoparticles in PANi matrix. The photocatalytic activities of nanocomposites were evaluated by using photo degradation of Methylene Blue (MB) in aqueous solution under UV irradiation. These nanocomposites exhibit much higher photocatalytic activity compared with TiO_2.
