Sonochemical synthesis of nanoplates of two Cd(II) based metal-organic frameworks and their applications as precursors for preparation of nano-materials

Nano plates of two Cd(II)-based metal-organic frameworks, [Cd-2(oba)(2)(4-bpdb)(2)](n)center dot(DMF)(x)(TMU-8) and [Cd(oba)(4,4'-bipy)](n)center dot(DMF)(y) (TMU-9) were synthesized via sonochemical reaction by using various time and concentrations of initial reagents and power of irradiation and characterized by scanning electron microscopy, X-ray powder diffraction and IR spectroscopy. Moreover, the effect of triethylamine on speed of nucleation during the synthesis was investigated. Thermolysis of these MOFs at 550 degrees C under air atmosphere yields CdO nanoparticles.
