Popis: In this study, the copper(II)–curcumin and copper(I)–curcumin complexes were immobilized onto the Mobil Composition of Matter No. 41 (MCM‐41) nanostructure, which have inherent advantages in the field of green chemistry and have been used as the catalyst for the removal of the carbazole (C12H9N) from the oil cut. The structures of the synthesized complexes were studied by Fourier-transform infrared spectroscopy (FT-IR), X-ray powder diffraction (XRD), energy-dispersive X-ray spectroscopy (EDS), field emission scanning electron microscopy (FESEM), differential thermal analysis (DTA), Brunauer–Emmett–Teller (BET), thermogravimetric analysis (TGA), Barret–Joyner–Halenda (BJH), and mapping techniques. Also, using the techniques and procedures in gas chromatography–mass spectrometry (GC–MS) were identified the products in the removal process. In this method, the use of Ultra-Violet (UV) light in the presence of a suitable solvent and perfect N-compounds removal from oil cut through advanced oxidation have led to the production of by-products that can function similarly to fuel octane number additives under an aldol condensation reaction. In this study, the performance of optimum catalyst was also compared under UV and visible light conditions.
