An apparatus to determine the vapor-liquid equilibria of CO(2)/ionic liquid (IL)/organic solvent multisystems and the viscosity of the liquid phase at elevated pressures has been constructed. The solubility of CO(2) in 3-butyl-1-methyl-imidazolium hexafluorophosphate ([C(4)mim][PF(6)]) and the viscosity of CO(2)-saturated [C(4)mim][PF(6)] have been studied… (More)
Mesoporous polyacrylamides (PAMs) with tunable porosities were synthesized in 1-alkyl-3-methylimidazolium tetrafluoroborates ([Cnmim][BF4], n = 4, 6, 8, 10). The as-synthesized PAM was used as a support for Pd nanoparticles and the Pd/PAM composite showed high catalytic activity and selectivity for the hydrogenation of p-chloronitrobenzene reaction to yield… (More)
Alpha-chymotrypsin (CT)/polyvinylpyrrolidone (PVP) composites was synthesized by combination of reverse micelles and CO(2). In this method, the two reverse micellar solutions containing CT and PVP, respectively, were first mixed, then compressed CO(2) was used as an antisolvent to precipitate the CT and PVP simultaneously and CT/PVP composites were… (More)
The emulsification of metal-organic frameworks (MOFs) for the two immiscible phases of water and ionic liquid (IL) was investigated for the first time. It was found that Ni-BDC (BDC = 1,4-dicarboxybenzene) can emulsify water and ILs and favor the formation of high internal phase emulsions (HIPEs) under certain experimental conditions. The microstructures of… (More)
The effect of water and several organic solvents on the density, viscosity, and conductivity of ionic liquids (ILs) 1-n-butyl-3-methylimidazolium hexafluorophosphate ([bmim][PF6]), 1-n-butyl-3-methylimidazolium tetrafluoroborate ([bmim][BF4]), and 1-n-butyl-3-methylimidazolium trifluoroacetate ([bmim][CF3CO2]) was studied at 298.15 K in wide composition… (More)
Graphene/polyaniline composite nanosheets can be prepared with the aid of polymerized ionic liquid, and both individual nanosheets and stable aqueous dispersions of the nanosheets can be obtained.
The mesoporous metal-organic frameworks are a family of materials that have pore sizes ranging from 2 to 50 nm, which have shown promising applications in catalysis, adsorption, chemical sensing and so on. The preparation of mesoporous metal-organic frameworks usually needs the supramolecular or cooperative template strategy. Here we report the… (More)
Emulsions composed of an ionic liquid (IL) 3-methyl-1-octylimidazolium hexafluorophosphate, water, and surfactant TX-100 (poly(ethylene glycol)-tert-octylphenyl) were studied by laser confocal scanning microscopy, stability determination and electrical conductivity. Multiple water-in-ionic liquid-in-water (W/IL/W) emulsions were formed around water volume… (More)
Mesoporous MOF nanoplates were formed in surfactant-IL solutions. This method is simple, requires less energy, and is environmental friendly, and can be easily applied to the synthesis of other MOFs with different morphologies and porosities.
Here we demonstrate the in situ formation of ultra-small gold nanoparticles (<2 nm) finely dispersed on a binary solid carrier, i.e. a mesoporous SiO2 coated graphene oxide (GO) nanosheet. The as-synthesized Au-SiO2-GO composite has shown high catalytic activity and reusability for chemical reactions under mild conditions.
