Synthesis and characterization of new photocatalyst-based tin (IV) 5, 10, 15, 20-tetrakis (4-benzhydryl benzoate) porphyrin immobilized on Fe3O4 nanoparticles for removal of organic dye from wastewater

In this research, tin (IV) 5,10,15,20-tetrakis 4-benzhydryl benzoate porphyrin (dented as Sn-TBhBP) as a new type of metalloporphyrin was synthesized and immobilized on the surface of FeO nanoparticles (NPs). The characterization of nanocomposite was carried out by Fourier transform infrared (FT-IR), ultraviolet–visible (UV–vis), X-ray diffraction (XRD), energy dispersive X-ray (EDX), scanning electron microscopy (SEM), fluorescence spectroscopy (FLS), Brunner-Emmett-Teller (BET), transmission electron microscopy (TEM), and differential reflectance spectroscopy (DRS) methods. The catalytic activity of the Sn-TBhBP@FeO was investigated as a new photocatalyst in the degradation of methylene blue (MB) under visible light irradiation. The results indicated that the maximum efficiency was achieved with a dye concentration of 10 ppm, resulting in a MB degradation rate of 98 % in the presence of Sn-TBhBP@FeO photocatalyst. Moreover, a prospective mechanism for the developed photocatalytic performance was proposed. The present study demonstrated the possible applications of the Sn-TBhBp@FeO photocatalyst for the environment issues.
