The present paper describes the successful synthesis and application of a ternary hybrid consists of gold nano particles decorated on titania-polyaniline (TiO2-PANI-AuNPs) for A(3)-coupling between aldehydes, terminal alkynes and amines under visible irradiation. The synthesis of ternary hybrid involved the coating of PANI on TiO2 via an oxidative polymerization method followed by the deposition of AuNPs on TiO2-PANI using trisodium citrate as a reducing agent. The synthesized photocatalyst was characterized by various techniques like FT-IR, SEM, HR-TEM, XRD, UV-VIS, ICP-AES, TGA, XPS and PL spectroscopy. The synthesized photocatalyst exhibited higher efficiency which was presumed due to the suppressed electron-hole recombination and better electron mobility at the surface of the photocatalyst. In the hybrid, polyaniline was found to enhance the activity as well as stability of the photocatalyst owing to its chemical interaction with titania and gold. Furthermore, after the reaction, the photocatalyst could readily be recovered and recycled for several runs with consistent photo activity.
