Hole transporting glass-forming low-molar-mass hydrazones containing 3,4-ethylenedioxythiophene moiety were synthesized and characterized by nuclear magnetic resonance, infrared spectroscopy, and mass spectrometry. The thermal, optical and photoelectrical properties of the synthesized compounds ...
Mononuclear and binuclear metal complexes of hydrazone oxime resulted from the condensation of acetohydrazide and pyridyl hydrazide with 3-(hydroxyimino) butan-2-one were prepared. All compounds were characterized using elemental, spectral and thermal analyses, as well as magnetic moment and mol...
Graphitic mesoporous carbon (GMC) supported Ce-doped nickel catalyst was prepared by a simple incipient wetness impregnation and calcination method. The catalytic performance of the prepared catalyst was tested by catalytic steam reforming of toluene (a biomass tar model compound). Compared with...
The photocatalytic oxidation of gaseous benzene, toluene and xylene (BTX) over un-doped, 0.1 and 1 wt% Mn-TiO2 nanoparticles under ultraviolet and visible irradiation was studied in atmosphere of synthetic air or inert gas. The photocatalytic decomposition efficiency and the oxidation products w...
A ferric nitrate-promoted cross-dehydrogenative coupling reaction of N-hydroxyphthalimide (NHPI) with toluene derivatives is reported. The reaction proceeded smoothly using molecular oxygen as an oxidant, providing an efficient method for the synthesis of N-hydroxyimide esters. Furthermore, a pl...
The electrochemical reduction of liquid toluene to methylcyclohexane (MCH) was investigated using a membrane electrode assembly (MEA) and high active-area catalysts commonly used in proton exchange membrane fuel cells (PEMFC). The current density on Pt/C was higher than on PtRu/C, which was comp...
A green and in-situ metal-organic framework (MOF) shaping strategy was proposed to fabricate cellulose foam HKUST-1 and modify with polysaccharides for convenient adsorption applications. The obtained unique foam HKUST-1 not only maintains HKUST-1 intrinsic thermal stability and high surface are...
Recently, photo-thermocatalysis has been intensively motivated since it is beneficial for both relieving energy consumption and using the full solar spectrum energy. In this work, efficient photo-promoted thermocatalytic removal of VOCs has been investigated on ACo2O4 (A = Ni, Cu, Fe, Mn) spinel...
The non-framework aluminum is inevitably formed in the process of preparing the ultra-stable Y zeolite (USY), which severely blocks the mesopores of USY zeolite. It is necessary to treat the USY with the appropriate acid and/or alkali. In this paper, the USY zeolite is firstly dealuminated with ...
The preparation of size-controlled materials has shown remarkable potential with regard to their reinforced sensing performance. Herein, we report a facile solvothermal synthesis of dispersed WO3 nanoparticles with porous nanostructure caused by particle assembly. Various characterizations of th...
CuMn mixed oxides catalysts doped with La were prepared following a co-precipitation method and used for the catalytic oxidation of toluene. Catalysts properties of the catalysts were investigated by X-ray diffraction, N2 adsorption/desorption, scanning electron microscopy, H2-temperature-progra...
We used an impregnation method to prepare CuO/AC (activated carbon) composite materials of different CuO content and characterized them via scanning electron microscope (SEM), Brunner–Emmett–Teller (BET), and Fourier transform infrared spectroscopy (FT-IR). The effect of CuO content on toluene...
Arenesulfonyl chlorides undergo desulfonylative homo-coupling upon heating with hexamethyldisilane in the presence of Pd2(dibenzylideneacetone)3·CHCl3 as a precatalyst to afford biaryls. Diaryl sulfides are occasionally formed as byproducts.
Deep eutectic solvents (DESs) have emerged as potential green and low-cost substitutes to ionic liquids in various chemical processes. In this study, experimental activity coefficients at infinite dilution for 22 organic solutes were measured in the DES consisting of tetramethylammonium chloride...
Solute retention data acquired by gas-liquid chromatography were used to determine the activity coefficients at infinite dilution for 24 organic solutes in the deep eutectic solvent (DES) consisting of tetramethylammonium chloride and glycerol in a molar ratio of 1.001:2. The organic solutes inc...
7-hydroxy-TTNN, a possible metabolite of the aromatic retinoid: 6-(5,6,7,8-tetrahydro-5,5,8,8-tetramethyl-2-naphthyl)-2-naphthoic acid (TTNN) (2), was synthesized through a short route, the key step of which was a one pot oxidation/cyclisation/aromatisation of a 1,5 diol to afford the phenolic r...
Starting from N-(3′-acetoxyphenyl)trimellitimide a semicrystalline homopoly(ester-imide) was prepared by thermal polycondensation in bulk. Furthermore, a series of copoly(ester-imide)s was prepared by cocondensation with 4-acetoxybenzoic acid (4-HBA). With a 4-HBA content up to 40 mol% the melt...
The dynamic mechanical moduli have been determined in tension and torsion for oriented thermotropic liquid crystalline polymers formed by copolymerization of 4-hydroxybenzoic acid and 2-hydroxy 6-naphthoic acid. The behaviour has been interpreted in terms of an aggregate model of units of struct...
X-ray fibre diagrams of fibres drawn from the (liquid crystalline) melts of copoly(4-hydroxybenzoic acid/2-hydroxy-6-naphthoic acid) show meridional maxima that are aperiodic. The positions of these maxima are reproduced in calculations of the meridional intensities for completely random copolym...
The copolyester comprising 73 mol% of 4-hydroxy benzoic acid and 27 mol% of 6-hydroxy-2-naphthoic acid, so called Vectra, was known to show the strong second harmonic generation (SHG) when it has a high molecular weight. Using high-resolution solid state 13C NMR, we investigated the intermolecul...
