Ultrasound and modulation assisted synthesis of {[Cu(BDC-NH)(dabco)]DMF.3HO} nanostructures; New precursor to prepare nanorods and nanotubes of copper(II) oxide

Abstract

Nanostructures of porous coordination polymer {[Cu2(BDC-NH2)2(dabco)]DMF.3H2O} (1) have been synthesized in the presence of acetic acid as a modulator via sonochemical method. Different concentrations of metal ions, organic linkers, modulator reagent and also different sonication times were held to improve the quality and distribution of nanostructures. Ultrasound irradiation helps to nucleation step of the oriented attachment of modulation method and nanorods of compound 1 has been prepared. Compound 1 was calcinated at 500°C to prepare nanorods and nanotubes of copper(II) oxide. Compound 1 and CuO nanostructures were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM) and high resolution transmission electron microscopy (HR-TEM), X-ray powder diffraction (XRD) and thermal gravimetric analysis (TGA).

Design and synthesis of coordination polymers with chelated units and their application in nanomaterials science

“…Size and morphology of the produced nanomaterials are highly dependent on the type and morphology of the CP precursor. 52,[329][330][331] Porous g-Fe 2 O 3 nanoparticles were prepared via a solid-state transformation process of a mesoporous iron(III) carboxylate crystal, MIL-100(Fe). 332 The N 2 adsorption-desorption analysis also demonstrates the mesoporous character of the derived g-Fe 2 O 3 material, with type IV N 2 isotherm at 77 K. This material has a relatively large specic surface area 123.5 m 2 g À1 , which is presumed to be beneted from the two-step calcination of the template MIL-100(Fe).…”

Solid-state thermal conversion of a nanoporous metal–organic framework to a nonporous coordination polymer

“…21 In this method, the secondary building units of MOF that are mostly composed of metal oxide clusters in angstrom scale were transformed into metal oxide nanomaterials by thermal treatments. Search in the case of fabrication nanomaterials from metal-organic frameworks, as new precursors, indicates that nanomaterials such as ZnO nanoparticles from [Zn 2 (btec)(DMF) 2 ] n , (btec ¼ 1,2,4,5-benzenetetracarboxylate, DMF ¼ N,N-dimethylformamide), 22 Zn 2 (1,4bdc) 2 (dabco), (1,4-bdc ¼ 1,4-benzenedicarboxylate, dabco ¼ 1,4diazabicyclo[2.2.2]octane), 23 TiO 2 nanoparticles from MIL-125 and MIL-125-NH 2 , 24 CuO nanostructures from {[Cu 2 (BDC-NH 2 ) 2 (dabco)]DMF$3H 2 O, 25 and Co 3 O 4 nanoparticles from Co 3 (NDC) 3 (DMF) 4 , (NDC ¼ 2,6-naphthalene-dicarboxylate; DMF ¼ N,N 0 -dimethyl formamide) 26 were prepared. In addition to metal oxide nanomaterials, metal-organic frameworks also can be used for preparation of porous carbons.…”

A new lanthanum(III) complex, [La(MO)3(DMF)3(H2O)2] (MO = methyl orange), and La2O2SO4 nanoparticles; electrocatalytic activity for adsorption/desorption/evolution of hydrogen

“…The complex has no weight loss before 85 o C, but exhibits two main steps of weight losses at higher temperatures. The first weight loss starts at 240 o C and is complete at 300˚C, which can be attributed to the removal of DMF and H 2 O from the complex [63]. Finally, the second weight loss covers a temperature range from 380 to 440 o C, which is corresponded to the thermal decomposition of the MO ligands.…”
