摘要
Abstract A novel nanocomposite was synthesized by covalent functionalization of graphene oxide (GO) with 5,10,15,20‐tetrakis(4‐hydroxyphenyl)porphyrinatoiron (III) chloride (Fe−THPP) via an ester linkage. The synthesized nanocomposite was characterized by various techniques such as XPS, Raman spectroscopy, BET, IR, UV‐Visible, TGA, SEM, and EDX. The synthesized nanocomposite exhibited appreciable interaction with crystal violet (CV) dye with a detection limit of 2.6×10 −6 μg/mL and binding constant of 35.93×10 3 ppm −1 which ensured the high concentration of CV dye on the surface of synthesized photocatalyst. The nanocomposite was effectively utilized in the photo‐degradation of CV dye under visible light irradiation. The photo‐degradation efficiency was remarkably high (93.45 %) with a low catalytic dosage of 0.4 mg/L within 80 minutes. The nanocomposite exhibited good stability and reusability and thereby can be used in the photocatalytic degradation processes to treat wastewater.
