In this study, the synergistic effect between polyaniline and TiO2 nanoparticles make favorable accomplishment of aqueous methyl orange (MO) and methylene blue (MB) dyes. Before the degradation reaction, two-step methods were executed to prepare nanocomposite (TiO2/polyaniline) systems. Apart from synthesis, characteristics of the materials were perceived via x-ray diffraction, transmission electron microscopy, FOURIER transform infra red and UV-Vis techniques. The characteristic outcomes described the presence of polyaniline which suggestively impacts the size and crystallinity of TiO2 and additionally, initiate pi-pi* transition under visible light illumination. The pi-pi* transition was excited to generate more electrons and holes in the nanocomposites and it helps to achieve visible light degradation of MO and MB.
