Polyaniline (PANI)-wrapped TiO2 nanorods (PANI/TiO2), obtained through the oxidative polymerization of aniline at surface hydrothermally presynthesized nanorods, were evaluated as photocatalysts for degradation Bisphenol A (BPA). Fourier-transform infrared spectroscopy analysis revealed successful incorporation PANI into by appearance peaks 1577 and 1502 cm-1 that are due to C=C C-N stretch benzenoid or quinoid ring in PANI. Brunauer-Emmett-Teller PANI/TiO2 had almost double area (44.8999 m2/g vs 28.2179 m2/g). Transmission electron microscopy (TEM) showed with different diameters synthesized. The TEM a thin layer wrapped nanorods. X-ray photon survey scan nanocomposite presence C, O, Ti, N. Photocatalytic activity evaluation under UV radiation effect key parameters, including pH, contact time, dosage, initial concentration BPA, was carried out batch studies. Within 80 min, 99.7% 5 ppm BPA attained using 0.2 g/L photocatalyst pH 10. quantum yield (QY) these be 9.86 × 10-5 molecules/photon 2.82 TiO2, respectively. better performance than as-synthesized rate constant 4.46 10-2 min-1 compared 2.18 min-1. also superior (150 mmol/g/h 74.89 mmol/g/h). Nitrate ions increased while humic acid consistently inhibited BPA. LC-MS identified products m/z 213.1, 135.1, 93.1. reused up five cycles removal least 80% fifth cycle. results three possible intermediates. which included protonated [C14H13O2+], [C9H11O+]. demonstrated photocatalytic respect improved QY figure merit lower energy consumption.
