Facile polystyrene/ZnO/Fe3O4 nanocomposites prepared via a hydrothermal approach for enhancement of MB dye degradation
Research on Chemical Intermediates - Tập 45 - Trang 287-301 - 2018
In this present work, polystyrene/ZnO and polystyrene/ZnO/Fe3O4 nanocomposites (NCs) were prepared by a hydrothermal synthesis method. The crystalline nature of the prepared material was studied based on PXRD analysis. The presence of various functional groups in the resultant material was primarily confirmed from FT-IR spectra. The various defect levels [oxygen interstitials (Oi), oxygen vacancie...... hiện toàn bộ
Synthesis of strongly cationic hydrophobic polyquaternium flocculants to enhance removal of water-soluble dyes in wastewater
Research on Chemical Intermediates - Tập 43 - Trang 3395-3413 - 2016
A series of new hydrophobic and strongly cationic poly(dimethyldiallylammonium chloride)s (HC-PDMDAACs) were synthesized and used to enhance the removal of water-soluble dyes in dyeing wastewater. The water-soluble anionic dyes could be removed from the water phase by forming flocculation precipitations with strongly cationic units in the main chains of HC-PDMDAAC through electrostatic interaction...... hiện toàn bộ
Synthesis and structure of novel 6-(pyrazol-1-yl)-4-methyl-1H-pyrazolo[3,4-b]pyridin-3-ol derivatives
Research on Chemical Intermediates - Tập 40 Số 1 - Trang 239-247 - 2014
New 6-(pyrazol-1-yl)pyrazolo[3,4-b]pyridin-3-ol compounds were synthesized by cyclization reaction from 2,6-dichloro-4-methylnicotinonitrile. Their derivatives exist as the 3-hydroxy tautomer. The structure of the compound 1a of one of the resulting compounds was studied in detail by X-ray diffraction.
Silica-coated magnetic nanoparticles functionalized cobalt complex: a recyclable and efficient catalyst for the C−C bond formation
Research on Chemical Intermediates - Tập 47 - Trang 4113-4128 - 2021
In this study, the Co-based catalyst was prepared by cobalt immobilization on the surface of functionalized silica-coated magnetic NPs (Fe3O4@SiO2-CT-Co) as a magnetically core–shell nanocatalyst and characterized by FT-IR, TGA, XRD, VSM, SEM, TEM, EDX, EDX mapping, and ICP techniques and appraised in the Suzuki–Miyaura cross-coupling reaction under mild reaction conditions. The results displayed ...... hiện toàn bộ

Synthesis and characterization of activated carbon@zerovalent iron–nickel nanoadsorbent for highly efficient removal of Reactive Orange 16 from aqueous sample: experimental design, kinetic, isotherm and thermodynamic studies
Research on Chemical Intermediates - - 2019
A simple and fast method based on activated carbon@nanozerovalent iron–nickel (AC@nZVI/Ni) nanoadsorbent was developed for highly efficient removal of Reactive Orange 16 (RO16) from aqueous samples. AC@nZVI/Ni nanoadsorbent was characterized by FT-IR, XRD, SEM and EDX. Effects of diverse factors including the solution value, adsorption time, AC@nZVI/Ni dosage and initial RO16 concentration were ex...... hiện toàn bộ
Cerium salt as green corrosion inhibitor for steel in acid medium
Research on Chemical Intermediates - Tập 41 - Trang 49-62 - 2013
The inhibition performance of cerium sulphate tetrahydrate on the corrosion of steel in 1.0 M HCl solutions was investigated by using chemical (weight loss), electrochemical (electrochemical frequency modulation, electrochemical impedance spectroscopy, potentiodynamic polarization) and atomic force microscopy (AFM) at 25 ± 1 °C. Cerium sulphate tetrahydrate gave sufficient inhibition for the steel...... hiện toàn bộ
Influence of TiO2 impregnated with a novel copper(II) carboxylic porphyrin and its application in photocatalytic degradation of 4-Nitrophenol

The effects of current density and saccharin addition on the grain size of electroplated nickel
Research on Chemical Intermediates - Tập 41 - Trang 4141-4149 - 2014
Nanocrystalline nickel (Ni) coatings were synthesized by direct current electrodeposition at current density from 1 to 30 mA/cm2 and pH 4. The basic composition of the bath, which was prepared by dissolving Ni metal particles in HCl, was 0.2 M Ni ions. The effects of the current density and saccharin addition on the average particle size of Ni deposits were investigated by XRD and SEM techniques. ...... hiện toàn bộ
