| Abstract: | Magnetic nanoparticles, Fe3O4, have been prepared and functionalized by (N-(3-(triethoxysilyl)propyl)isonicotinamide) and characterized by infrared spectroscopy, thermal analysis (TGA/DTA), X-ray
powder diffraction, scanning electron microscopy, elemental analysis and BET surface area measurement. The functionalized
Fe3O4 nanoparticles were used as a support to anchor metalloporphyrin. Application of immobilized metalloporphyrin as a heterogeneous
catalyst in the oxidation of cyclohexene was explored. Effect of various parameters such as solvent and temperature on immobilization
process and also various parameters (solvent, time, oxidant and axial group effect) on oxidation of cyclohexene has been investigated.
The result showed that the immobilized metalloporphyrin on functionalized magnetic nanoparticles is an efficient and reusable
catalyst for oxidation of cyclohexene. |
