Abstract In this study, novel polyaniline-coated perovskite nanocomposites (PANI@CoTiO 3 and PANI@NiTiO ) were synthesized using an in situ oxidative polymerization method evaluated for the photocatalytic degradation of Rhodamine B (RhB) a persistent organic pollutant. The displayed significantly enhanced efficiency compared to pure perovskites. 1%wt achieved impressive 94% RhB under visible light after 180 min, while 1wt.% PANI@CoTiO3 reached 87% UV same duration. X-ray diffraction (XRD) confirmed that crystalline structures CoTiO NiTiO remained intact post-polymerization. At time, Fourier transform infrared spectroscopy (FTIR) verified successful deposition PANI through characteristic functional group vibrations. Diffuse reflectance (DRS) revealed reduced band gaps 2.63 eV 2.46 PANI@CoTiO , enhancing absorption across ranges. Scanning electron microscopy (SEM) energy dispersive (EDS) analysis demonstrated uniform distribution PANI, ensuring consistent surface activity efficient charge transfer. test pseudo-first-order mechanism. study elucidates mechanism intermediate identification via HPLC-MS analysis, highlighting N-de-ethylation, aromatic ring cleavage eventual mineralization into CO 2 H O as critical pathways. Furthermore, 1wt.%PANI@NiTiO nanocomposite excellent stability recyclability, maintaining its over four consecutive cycles with minimal change. These findings highlight potential PANI@XTiO sustainable wastewater treatment, addressing diverse environmental challenges by tailoring photocatalysts specific sources.
