fuel cells, secondary batteries and capacitors are among many promising energy storage devices. in particular, supercapacitors have attracted much attention because of their long life cycle and high power density. graphene/nickel ferrite(g-nf) based supercapacitors were successfully fabricated through a one-step facile solvothermal route. effects of synthesis conditions i.e. solvothermal time a...

Two 3d-4f heterometallic compounds of p-tert-butylsulfinylcalix[4]arene were synthesized by the solvothermal method and characterized by some hinged double-dumbbell-like subunits in which two perpendicular dumbbell entities were constructed by an in-between isosceles triangle Mn(II)Ln(III)(2), and two tail-to-tail calixarene molecules, and hinged by the lanthanide-sulfinyl group bonding. The ma...

IRMOF-3 nano/microcrystals with controllable morphologies and sizes were successfully obtained by a simple solvothermal method. The shape evolution of IRMOF-3 crystals from cube to truncated cube, cuboctahedron, truncated octahedron and finally to octahedron was achieved by adjusting the amount of surfactant. The surfaces of the IRMOF-3 nano/microstructures are affected by the reaction temperat...

Zinc oxide (ZnO) is a promising material which gained increasing interest in recent years owing to its preparation methods and remarkable performances. The paper presents the most common techniques for the synthesis of ZnO nanoparticles, such as mechanochemical process, precipitation, sol-gel method, solvothermal and hydrothermal processes. Due to their optical, mechanical, chemical and electri...

Single-crystalline TiOF(2) crystals with cubical morphology were prepared via a facile solvothermal method and their transformation to anatase TiO(2) under different calcination conditions such as pure argon, moist argon and pure hydrogen sulfide (H(2)S) was explored by using XRD/Raman/UV-Vis/SEM/TEM/SAED. The non-metal sulfur doping was successfully fulfilled and the doped TiO(2) microcubes sh...

CoFe2O4 nanoparticles were uniformly anchored on reduced graphene oxide by a facile solvothermal method. The obtained CoFe2O4/reduced graphene oxide (CoFe2O4/rGO) hybrid was employed as catalyst for Li-O2 batteries. It could effectively lower the ORR (oxygen reduction reaction) and OER (oxygen evolution reaction) overpotentials of the batteries and deliver a large capacity of 12 235 mA h grGO(-...

A solvothermal method was developed to prepare on a large scale monodisperse porous β-Co(OH)(2) microspheres consisting of nanoplatelets. Co(3)O(4) microspheres with porous platelets were obtained via subsequent thermal decomposition. These Co(3)O(4) microspheres show much higher ethanol sensitivity and selectivity at a relatively low temperature (135 °C) compared with those of commercial Co(3)...

Two semiconducting hybrid gallium selenides, [Ga6Se9(C6H14N2)4][H2O] (1) and [C6H14N2][Ga4Se6(C6H14N2)2] (2), were prepared using a solvothermal method in the presence of 1,2-diaminocyclohexane (1,2-DACH). Both materials consist of neutral inorganic layers, in which 1,2-DACH is covalently bonded to gallium. In 1, the organic amine acts as a monodentate and a bidentate ligand, while in 2, bident...

The new 3,5-(substituted) pyrazoles and isoxazoles were prepared by reaction of (N'(1)E, N'(3)E)- N'(1), N'(3)-bis (3,4,5-substitutedbenzylidene)malonohydrazide with hydrazine hydrate and hydroxylamine hydrochloride respectively under solvothermal conditions involving an ecofriendly method without any environmental pollution, the yield are in the range of 75-96%. The structure of the new compou...

There is a great deal of current interest in the development of rechargeable sodium (Na)-ion batteries (SIBs) for low-cost, large-scale stationary energy storage systems. For the commercial success of this technology, significant progress should be made in developing robust anode (negative electrode) materials with high capacity and long cycle life. Sn-P compounds are considered promising anode...
