Enhanced photocatalytic degradation of Rhodamine B using polyaniline-coated XTiO₃(X = Co, Ni) nanocomposites.

ABSTRACT: In this study, novel polyaniline-coated perovskite nanocomposites (PANI@CoTiO₃ and PANI@NiTiO₃) were synthesized using an in situ oxidative polymerization method and evaluated for the photocatalytic degradation of Rhodamine B (RhB) a persistent organic pollutant. The nanocomposites displayed significantly enhanced photocatalytic efficiency compared to pure perovskites. The 1%wt PANI@NiTiO₃ achieved an impressive 94% degradation of RhB under visible light after 180 min, while 1wt.% PANI@CoTiO3 reached 87% degradation under UV light in the same duration. X-ray diffraction (XRD) confirmed that the crystalline structures of CoTiO₃ and NiTiO₃ remained intact post-polymerization. At the same time, Fourier transform infrared spectroscopy (FTI
