Preparation of honeycomb magnetic Co۳O۴ nanostructures from trans, trans, trans- [Co(py)۲(H۲O)۲(SCN)۲] as a new precursor; Synthesis and Reactivity in Inorganic, Metal-Organic, and Nano-Metal Chemistry

چکیده مقاله

Co3O4 nanostructures were synthesized via a facile thermal treatment method by using the trans,trans, trans- [Co(py)2(H2O)2(SCN)2] as a new precursor. In synthetic process Co-complex was synthesized by reaction of KSCN via trans, trans, trans-[Co(py)2(H2O)2(NO3)2]. Results show that changing on temperature to 400 oC caused to preferential growth and formation of the honeycomb nanostructures. Nanostructures were characterized by scanning electron microscope, X-ray diffraction, UV–visible, Fourier transformed infrared spectroscopy and alternating gradient force magnetometer. It’s found that the Co3O4 nanostructures exhibit a ferromagnetic behavior with a saturation magnetization of 16.6 emu/g and a coercivity of 251.4 Oe at room temperature.
