We present a novel approach for enhancing photocatalytic efficiency by developing polyaniline (PANI) and polyindole (PIN)-coated TiO2 nanotubes (TNT) through combination of chemical oxidation hydrothermal processes. The PANI–PIN coating was systematically applied to both the internal external surfaces enhance active sites optimize pollutant adsorption. dual-coated structure enhances interaction with pollutants, facilitating more efficient degradation 4-nitrophenol (4-NP) when exposed visible light. Thorough characterization X-ray diffraction (XRD), Fourier-transform infrared (FTIR), field emission scanning electron microscopy (FE-SEM), transmission (TEM), energy-dispersive (EDX), N2-physisorption, transient photocurrent, diffuse reflectance spectroscopy (DRS), photoluminescence (PL) validated exceptional structural optical properties composite. PANI/PIN polymer effectively inhibited electron–hole recombination, leading notable enhancement in performance. Among tested composites, formulation consisting 75% PANI 25% PIN demonstrated remarkable performance, achieving rate 99.46% 4-NP only 120 min exposure impressive stems from its extensive surface area (255.3 m2/g), charge separation, minimized band gap (2.77 eV), improved light absorption. Moreover, composite recyclability, preserving catalytic activity across five cycles without any decline These results demonstrate strong potential 75%PPTN as promising photocatalyst environmental remediation.
