Metal-organic frameworks of cobalt and nickel centers with carboxylate and pyridine functionality linkers: Thermal and physical properties; precursors for metal oxide nanoparticle preparation

This  article  provides  an  overview  on  preparation,  design,  crystal structure  and  properties  of  some  metal-organic  frameworks  of carboxylate coordination polymers mixed with pyridine-functionality linkers  prepared  in  our  laboratory.  The  article  covers  coordination polymers  in  two-  and  three-dimensional  supramolecular architectures. The reported coordination polyme...

Synthesis of Different Copper Oxide Nano-Structures From Direct Thermal Decomposition of Porous Copper(ΙΙ) Metal-Organic Framework Precursors

Copper oxide nanostructures have been successfully synthesized via one-step solid-state thermolysis of two metal-organic frameworks, [Cu3(btc)2] (1) and [Cu(tpa).(dmf)] (2), (btc = benzene-1,3,5-tricarboxylate, tpa = therephtalic acid = 1,4-benzendicarboxylic acid and dmf = dimethyl formamide) under air atmosphere at 400,  500, and 600°C. It has also been found that the reaction temperature pla...

Synthesis and Characterization of Nano-Structure Copper Oxide From Two Different Copper (II) Metal-Organic Framework Precursors

Nano-structured copper oxides were successfully prepared through direct calcination of 1D ladderlike metal-organic framework [Cu2(btec)(2,2'-bipy)2]∞, (btec = 1,2,4,5-benzenetetracarboxylate and 2,2'-bipy = 2,2'-bipyridine) and porous coordination polymer [Cu(BDC)(bipy)](BDCH2), (BDC = 1,4-benzenedicarboxylate; bipy = 4,4'-bipyridine). The nano-structure of the as-synthesized samples are charac...

In this paper, the effect of nanocatalytic metal-organic framework based on copper metal and bis-tetrazolamine (CuBTA) ligand functionalized with cobalt (II) oxide nanoparticles on the thermal decomposition behavior of ammonium perchlorate (AP), using differential survey calorimetry (DSC) has been reviewed. First, the metal-organic framework (CuBTA) was synthesized from the raw materials of cop...

Synthesis and Characterization of Nanocrystalline Magnetic Pigment via Coordinated Precursors

Nanocrystalline cobalt ferrite as a magnetic black pigment was synthesized via coordinated precursors with a significant decrease of the synthesis temperature using citric acid as a coordinating agent. The structure and properties of the cobalt ferrite powder were characterized by X-ray diffraction (XRD), colorimetric analysis (L*a*b* color parameters), diffuse reflectance spectroscopy and vibr...
