The nanocomposite, </span><span style="background:yellow"><span style="background-color:#ffffff;">Titania-Polyaniline (Ti</span></span><span lang="EN-US" style="background:yellow"><span style="background-color:#ffffff;">O</span>_{<span style="background-color:#ffffff;">2</span>}<span style="background-color:#ffffff;">-PANI)</span></span><span style="background-color:#ffffff;"> was synthesized using the chemical oxidative polymerization method. Various characterization techniques were employed to assess the properties of the catalysts. </span><span style="background:yellow"><span style="background-color:#ffffff;">The ultraviolet diffuse reflectance spectroscopy</span></span><span style="background-color:#ffffff;"> (UV-DRS) analysis revealed that the TiO</span>_{<span style="background-color:#ffffff;">2</span>}<span style="background-color:#ffffff;"> absorbs only UV light while the TiO</span>_{<span style="background-color:#ffffff;">2</span>}<span style="background-color:#ffffff;">-PANI nanocomposite absorbs light from both UV and visible regions. The </span><span style="background:yellow"><span style="background-color:#ffffff;">X-ray diffraction</span></span><span style="background-color:#ffffff;"> (XRD) results confirmed the presence of TiO</span>_{<span style="background-color:#ffffff;">2 </span>}<span style="background-color:#ffffff;">(anatase) in both TiO</span>_{<span style="background-color:#ffffff;">2</span>}<span style="background-color:#ffffff;"> nanoparticles and TiO</span>_{<span style="background-color:#ffffff;">2</span>}<span style="background-color:#ffffff;">-PANI </span><span style="background:yellow"><span style="background-color:#ffffff;">(Titania-Polyaniline)</span></span><span style="background-color:#ffffff;"> &nbsp;nanocomposite. The phases of the catalysts were verified through Raman, TEM, and SAED techniques where all results are in good agreement with each other. The average crystallite size of TiO</span>_{<span style="background-color:#ffffff;">2</span>}<span style="background-color:#ffffff;"> nanoparticle and TiO</span>_{<span style="background-color:#ffffff;">2</span>}<span style="background-color:#ffffff;">-PANI nanocomposite were 13.87 and 10.76 nm. The thermal stability of the catalysts was assessed by the </span><span style="background:yellow"><span style="background-color:#ffffff;">Thermal gravimetric analysis</span></span><span style="background-color:#ffffff;"> (TGA) technique. The order of the thermal stability is TiO</span>_{<span style="background-color:#ffffff;">2</span>}<span style="background-color:#ffffff;"> > TiO</span>_{<span style="background-color:#ffffff;">2</span>}<span style="background-color:#ffffff;">-PANI > PANI. &nbsp;</span><span style="background:yellow"><span style="background-color:#ffffff;">The crystal lattice characteristics were confirmed using Transmission electron microscopy</span></span><span style="background-color:#ffffff;"> (TEM). </span><span style="background:yellow"><span style="background-color:#ffffff;">The surface area measurements were confirmed from the </span></span><span style="background:yellow"><span style="background-color:#ffffff;">Brunauer-Emmett-Teller (BET)</span></span><span style="background-color:#ffffff;"> study and were employed for the evaluation of the photocatalytic efficiency of both, TiO</span>_{<span style="background-color:#ffffff;">2</span>}<span style="background-color:#ffffff;"> nanoparticles and TiO</span>_{<span style="background-color:#ffffff;">2</span>}<span style="background-color:#ffffff;">-PANI nanocomposite catalysts. The </span><span style="background:yellow"><span style="background-color:#ffffff;">energy dispersive spectroscopy (EDS)</span></span><span style="background-color:#ffffff;"> </span><span style="background:yellow"><span style="background-color:#ffffff;">study was employed for elemental detection of the fabricated materials. While Raman spectroscopy was employed for the chemical structure and the phase characteristics of the materials.</span></span><span style="background-color:#ffffff;"> The standard conditions for the degradation of the CF dye were 8 g/L of catalyst dosage, 20 mg/L of dye concentration, and a pH of 7. The TiO</span>_{<span style="background-color:#ffffff;">2</span>}<span style="background-color:#ffffff;">-PANI nanocomposite exhibited superior efficiency as compared to pure TiO</span>_{<span style="background-color:#ffffff;">2 </span>}<span style="background-color:#ffffff;">nanoparticles, achieving almost 100 % degradation in just 40 minutes. &nbsp;</span></span></span></span> TiO2–PANI nanocomposite,Carbol fuchsin dye,TEM,Water purification 151 169 http://ijmse.iust.ac.ir/browse.php?a_code=A-10-5240-1&slc_lang=en&sid=1 Satish Ahire satishahirechem@gmail.com 1800319475328460020128 1800319475328460020128 No Department of Chemistry, Maharaja Sayajirao Gaikwad Arts, Science and Commerce College, Malegaon, Nashik (Affiliated to Savitribai Phule Pune University, Pune (MH), India) Ashwini Bachhav ashwini27212@gmail.com 1800319475328460020129 1800319475328460020129 No MVPs College of Pharmacy, Nashik.
