Supported Metal Organic Frameworks (MOFs) with a high specific surface area are of great interest for applications in gas storage, separation, sensing, and catalysis. In the present work we report the synthesis of a novel composite architecture of MOF materials supported on a flexible mat of electrospun nanofibers. The system, based on three-dimensional interwoven nanofibers, was designed by us...

Highly porous nanostructures with large surface areas are typically employed for electrical double-layer capacitors to improve gravimetric energy storage capacity; however, high surface area carbon-based electrodes result in poor volumetric capacitance because of the low packing density of porous materials. Here, we demonstrate ultrahigh volumetric capacitance of 521 F cm(-3) in aqueous electro...

CeO2-MO x (M = Cu, Co, Ni) composite yolk-shell nanospheres with uniform size were fabricated by a general wet-chemical approach. It involved a non-equilibrium heat-treatment of Ce coordination polymer colloidal spheres (Ce-CPCSs) with a proper heating rate to produce CeO2 yolk-shell nanospheres, followed by a solvothermal treatment of as-synthesized CeO2 with M(CH3COO)2 in ethanol solution. Du...

In our work, ciprofloxacin was extracted from the raw material ciprofloxacin hydrochloride and coordinated with the metal ions of copper, manganese and zirconium. The procedures include the comparison of the autoclave method with the solvothermal method, synthesizing the corresponding complexes and conducting antibacterial test on nearly 20 kinds of bacteria. It is shown that under the conditio...

The efficiency of thermochemical heat storage is crucially determined by the performance sorbent used, which includes a high sorption capacity and low regeneration temperature. salt hydrate– γ-alumina composite sorbents are promising materials for this application but lack systematic study influence structural properties on final performance. In study, mesoporous γ-Al2O3 supports were prepared ...

Zinc oxide nanoparticles (ZnO-NPs) were synthesized via a solvothermal method in triethanolamine (TEA) media. TEA was utilized as a polymer agent to terminate the growth of ZnO-NPs. The ZnO-NPs were characterized by a number of techniques, including X-ray diffraction analysis, transition electron microscopy, and field emission electron microscopy. The ZnO-NPs prepared by the solvothermal proces...

Nowadays, iron (II) selenide (FeSe), which has been widely studied for years to unveil the high-temperature superconductivity in iron-based superconductors, is drawing increasing attention electrical energy storage (EES) field as a supercapacitor electrode because of its many advantages. In this study, very small FeSe particles were synthesized via simple, low-cost, easily scalable, and reprodu...

   A simple low-cost solvothermal method was applied to synthesize hexagonal wurtzite Cu2ZnSnS4 (CZTS) nanoparticles with different morphologies using Polyvinylpyrrolidone (PVP) as a capping ligand and copper and zinc acetate salts at 180 and 220 ℃. The resulting sphere-like and flower-like nanoparticles synthesized at 180 and 220℃</...

The syntheses, crystal structures and magnetic properties are described for a {Co16} cluster [Co(II)16O(OH)2(bha)12(PhCO2)4(Phen)2(MeOH)4]·2MeOH (1) and a 1-D Mn(II) chain complex [Mn(Hbha)2]n·(2MeOH)n (2) (H2bha = benzohydroxamic acid; Phen = 1,10-phenanthroline). The 1 : 1 : 0.5 reaction of Co(O2CMe)2·4H2O, H2bha and 1,10-phenanthroline in MeOH at 100 °C under autogenous pressure gave cluster...

Solvothermal and microwave-assisted methods have been used to prepare several amidate and carboxylate complexes of the type [Ru2X(μ-NHOCC6H3-3,5-(OMe)2)4]n [X = Cl (1), Br (2), I (3)] and [Ru2X(μ-O2CC6H3-3,5-(OMe)2)4]n [X = Cl (4), Br (5), I (6)]. Complexes 4–6 have also been obtained by conventional synthesis which is ineffective to prepare the amidate compounds. However, single crystals of co...
