Abstract

The paper describes the synthesis of conducting polyaniline-TiO₂(PANI-TiO₂) nanocomposite by chemical oxidative polymerization method using aniline as a monomer. TiO₂nanoparticles were synthesized by sol gel method using TiCl₄ and ethanol. Ultrasound synthesized TiO₂ nanoparticles and nanocomposite were characterized by various spectroscopic techniques UV, FT-IR, XRD, SEM and TGA. The XRD pattern confirms the appearance of sharp diffraction patterns indicating the small sized, high purity TiO₂nano particles are highly agglomerated with spherical morphology. The PANI-TiO₂nanocomposite was employed as a promising heterocyclic, reusable catalyst for most of the organic synthesis. The advantages of this methodology are mild reaction conditions with short reaction time, excellent yields, low loading and reusability of catalyst.
