An iron (II) tetramethylated tetrapyridinoporphyrazine (FeII(2,3-tmtppa)) grafted onto sulfonated SBA-15 (SBA15@n-Pr-SO3@Fetmtppa)) has been synthesized. The catalyst was characterized using X-ray diffraction, nitrogen adsorption?desorption measurements, Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, transmission electron microscopy, thermogravimetric analysis and scanning electron microscopy. XRD, XPS and ICP analyses confirmed the incorporation of iron (II) ion onto the surface of functionalized support. TGA and BET diagrams, FESEM and TEM images showed the grafting of (FeII(2,3-tmtppa)) on SBA-15 with mesoporous structure and ordered channels after immobilization process. This catalyst is able to perform C-H oxidation reaction of alkanes including toluene and ethylbenzene derivatives in the presence of molecular oxygen under the mild reaction in water. The hot filtration and reusability tests of the catalyst were studied which showed that the C-H activation reaction proceeds via heterogeneous pathway and catalyst is recoverable for at least 5 times.
