Cobalt and Molybdenum oxides supported on graphene catalyst CoMo/G were prepared then its activity for hydro-desulfurization reaction HDS was examined in this research. The catalyst was characterized by X-ray diffraction XRD, Fourier transform infrared spectroscopy FTIR, and energy dispersive spectroscopy EDS while surface morphology was tested by scanning electronic microscopy SEM and atomic force microscopy […]
Mesoporous CoAl2O4 spinel nanocrystals ( nano-CoAl2O4 ) were synthesized and fully characterized by X- ray diffraction patterns (XRD), energy-dispersive X-ray spectroscopy (EDS), scanning electron microscopy (SEM), transmission electron microscopy (TEM), DLS (dynamic light scattering) and FT-IR. The nanocrystals promoted the preparation of quinazolinones via the one-pot, three component condensation reaction of benzaldehydes, isatoic anhydride, primary […]
Various magnetite heterogeneous catalysts for the organic reaction are increasingly recognized while their stability still is a critical challenge. In this regard, SiO2, ionic liquid (IL), and polyvinyl pyrrolidone (PVP) were applied as a three-layer stabilization system for modifying magnetic Fe3O4 to produce Fe3O4@SiO2@IL‐PVP as a novel nanocatalyst. The Fe3O4@SiO2@IL‐PVP as stabilized heterogeneous catalysts were […]
Cobalt-based perovskites containing strontium and copper (La1-xSrxCo1-yCuyO3) were synthesized by the sol-gel method and characterized by XRD, H2-TPR, N2-adsorbtion, XRF and XPS techniques. The XRD results showed that the rhombohedral structure of perovskites was obtained. The activation energy employed to analyze the activities of samples in the combustion of methane was optimized using full factorial […]
The main purpose of this study was to investigate the photocatalytic decomposition of the antibiotic Cefazolin (CFZ) from aqueous solutions using a new effective catalyst. This catalyst was made of α-Fe2O3-supported nanoparticles on a metal-organic framework (MOF). The synthesis of Nano α-Fe2O3 photocatalyst was performed by the reflux condensation method. The MOF was synthesized using […]
Si-Im/HSO4(1-methyl-3-(3-(trimethoxysilyl) propyl) imidazolium hydrogen sulphate functionalized Copper oxide nanoparticles(CuO NPs )as a novel supporting ionic liquid was prepared and characterized by FT-IR spectroscopy, FE-SEM, XRD, TGA, and EDX techniques. It was used as a recyclable catalyst for the one-pot, three-component synthesis of 1, 4- dihydro Pyrano [2, 3-c] pyrazoles derivatives. The results showed that the […]
The wet peroxide oxidation (CWPO) of phenol in the polluted water on Mg-Al nano mixed oxide was investigated and the optimization and kinetic of the process were studied. The nanocatalyst was characterized by XRD, FESEM, EDS and BET. The average crystallite size of 25 nm was estimated using Scherrer formula.FESEM images approved the catalyst comprised […]
A modified carbon paste electrode with NiO nanoparticles showed an excellent electrocatalytic behavior towards loratadine in the voltammetric and chronoamperometric approaches. Typical plots of IC/IL vs. t1/2 were contracted, and an average rate constant of 185.5 ± 2.2 M−1 s−1 was obtained from the slope of the curve. The geometric surface area of the electrode […]
