This paper reports the synthesis of visible light-active Ag@TiO2/Pani nanocomposite through a facile biogenic-chemical route. Ag@TiO2/Pani nanocomposite was prepared by the in-situ oxidative polymerization of aniline in the presence of Ag@TiO2 nanocomposite, which was obtained via a biogenic route. The synthesized Ag@TiO2/Pani nanocomposite was confirmed by UV-visible spectroscopy, photoluminescence spectroscopy, transmission electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy and thermogravimetric analysis. The Ag@TiO2/Pani nanocomposite was doped with HCl or para-toluene sulfonic acid to render it conducting. An analysis of the thermoelectrical behavior using a cyclic aging technique showed that the electrical conductivity and thermal stability of Pani got improved after …
