Super paramagnetic ZIF-67 metal organic framework nanocomposite

Nanoparticle encapsulated metal-organic framework composites have attracted attention in many fields owing to the achievement of combined properties. We report a simple method for the encapsulation of magnetite nanoparticles into zeolitic imidazolate framework-67 (ZIF-67). ZIF-67 framework is prepared by using Cobalt nitrate as metal salt by hydrothermal method. The material shows functional properties of both magnetite and ZIF-67. The bonding interactions are analysed by Fourier transform infrared spectroscopy. The microstructure and morphology are characterized by powder X-ray diffraction, scanning electron microscopy, and transmission electron microscopy. Magnetic measurements are inquired by vibrating sample magnetometry and surface area studies done by Bruner-Emmett and Teller surface area analysis technique.
