Magnetic nanoparticles, Fe 3 O 4 , 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 Fe 3 O 4 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.

Nano-structures of the Cu(II) metal-organic framework, {Cu(BDT)(DMF)·CH3OH·0.25DMF}n (1), which BDT(2-) is 1,4-benzeneditetrazolate, have been synthesized by the reaction of H2BDT with Cu(NO3)2·6H2O via ultrasonic irradiation in three different temperatures, which causes different morphologies. The products were characterized by IR spectroscopy, elemental analysis, scanning electron microscopy and X-ray powder diffraction. This study demonstrates that sonochemistry is a suitable method for preparation of metal-organic framework nano-structures and temperature is an effective parameter on morphologies of Cu(II) metal-organic framework nano-structures.
