In this paper, we report the synthesis of magnetically separable stable phosphors doped [email protected] and phosphors doped [email protected] nanocomposite with their application as retrievable visible-light photocatalyst. Their comparative performance is investigated for photo-degradation of a dye rhodamine B (RhB) as an organic pollutant. The Fe3O4 nanoparticles prepared via sol–gel assisted method and annealed at 200–400 °C. Phosphors doped g-C3N4 (PCN) prepared by adding NH4(H2PO4) to an aqueous solution of melamine and NiFe2O4 nanoparticles prepared by the simple sol–gel method followed by calcination. The crystal structure, morphology, microscopic components and properties of the synthesized samples characterized by XRD, SEM, TEM, photoluminescence (PL) emission spectroscopy, CV analysis for super capacitive nature and zeta potential. Two simplified kinetic models, pseudo-first-order and pseudo-second-order, were applied to predict the adsorption rate constants. The [email protected] showed excellent photostability and was able to evolve 904 µmol h−1 H2 in comparison to [email protected] (556 µmol h−1) under visible-light irradiation. The results reveal an approach to synthesized large scale ferrite nanoparticles, and improve the magnetic properties of ferrite nanoparticles, and also provide the potential candidates to synthesis co-doped functional magnetic materials.
