Abstract

Time and again, SBA-15-based composites as mesoporous materials and incorporating transition metals in them have been attracting dramatic attention in the field of catalysis due to their remarkable features. In this paper, the activity of SBA-15 supported ionic liquid-Pd(II) has been investigated in the catalytic transfer hydrogenation of nitroarenes with formic acid as a hydrogen donor at room temperature in water medium and oxidation of benzyl alcohols to benzaldehyde derivatives under atmospheric oxygen at high temperature. This novel nanocatalyst was characterized by FT-IR, SA-XRD, BET, BJH, TGA, FE-SEM, TEM, and ICP as most commonplace techniques for analyzing its characteristics to be revealed truth. Furthermore, the EDX analysis illu

Abstract

A special composite of the cerium-based metal–organic framework (Ce-UiO-66) modified with graphitic carbon nitride nanosheets (g-C3N4) has been synthesized. In order to make a comparison, a series of composites comprising g-C3N4 and Ce-MOF was synthesized as well. Their structural features were investigated using Fourier transform infrared spectroscopy (FT-IR), Powder X-ray Diffraction (PXRD), sorption of nitrogen (BET and BJH), Thermo-gravimetric Analysis (TGA), Scanning Electron Microscopy (SEM), Energy Dispersive X-Ray (EDX), Transmission Electron Microscopy (TEM), X-Ray Fluorescence Spectroscopy (XRF) and Diffuse Reflectance UV–Vis Spectroscopy (UV-Vis DRS) and Electron Spin Resonance (ESR) techniques. According to the obtained resu

Abstract

In the present study, a novel and magnetically separable Pd−catalyst system was designed using the immobilization of PdII on Phendioxime(PDO)‐functionalized magnetic partially reduced (GO‐OMWCNT) composite (MPR (GO‐OMWCNT)/PDO/PdII). In the as‐obtained nanocomposites, the incorporation of 1D OMWCNTs and 2D graphene oxide can form a versatile 3D network with high specific surface area and synergic properties. Moreover, non‐ covalent phendioxime functionalization provides highly effective functional groups on the surface of MPR (GO‐OMWCNT) for PdII. Non‐covalent interaction carries out through π‐π stacking and hydrogen bond interactions .The catalytic activity of this nanocomposite was examined in the Suzuki–Miyaura cro

Abstract

Ce-UiO-66 MOF, namely cerium-organic framework was prepared through a fast and efficient method under ultrasonic radiation. After preparation, it was identified using some different microscopic and spectroscopic techniques such as PXRD, FT-IR, TG/DTA, BET, BJH, and FE-SEM. The catalytic activity of Ce-UiO-66 MOF was checked in aerobic oxidation of methyl arenas, alcohols and styrene derivatives in a sustainable circumstance with no additives. Moreover, its catalytic activity was surveyed influenced by a number of variables in the ultrasonic synthesis method. Some parameters such as solvent, base, temperature, amount of the catalyst and time were also tested to optimize the aerobic oxidation reaction. After the 10th run, the recycled Ce-MOF

A sustainable approach for efficient one‐pot synthesis of 1‐aryl 1, 2, 3‐triazoles using copper iodide supported on 3‐thionicotinyl‐urea‐modified magnetic nanoparticles in DES

Abstract

An efficient and retrievable copper(I) catalyst was synthesized by immobilizing of copper iodide on 3‐thionicotinyl‐urea‐modified magnetic nanoparticles and characterized using a variety of analysis techniques. The catalytic activity of these nanoparticles was investigated in the one‐pot three‐component reaction of aryl halides, sodium azide, and terminal alkynes using choline chloride/PEG deep eutectic mixture as a green and recoverable solvent. The PEGylated deep eutectic solvent (DES), due to its favorable polarity and solubility, can make an effective association of polar and non‐polar reactants during the reaction, thereby accelerating the catalysis process. An array of 1‐aryl 1,2,3‐triazoles were obtained in good to ex

Abstract

The synthesis of tetrazoles by Fe3O4@Phenyl phosphate creatine as a catalyst has been reported previously. In this article, the optimized geometry of the tetrazole derivatives and Fe3O4@Phenyl phosphate creatine have been computed with the help of density functional theory (DFT). The detailed interpretations of HOMO–LUMO and molecular electrostatic potential surfaces on the tetrazole derivatives and Fe3O4@Phenyl phosphate creatine were carried out at the B3LYP/6-31+G(d) level of theory that are useful tools for molecular stability prediction. Finally, molecular docking was used as an effective method to describe the biological activity of tetrazole derivatives.

Abstract

Herein, a nano acid-base catalyst using magnetic core and carbamodithioic acid functional group have been synthesized and characterized. Its efficiency in the synthesis of dihydroquinazolinones and bis(indolyl)methanes derivatives was investigated. This novel metal-free catalyst exhibited significant catalytic activity in both reactions under green and mild reaction conditions (the yield obtained for the first reaction products: 82–98 % and for the second one: 61–97 %). The catalyst displayed good recyclability with no significant loss of catalytic activity after eight runs (the conversion of the eighth run was found as 83 %, the fresh catalyst conversion was 95 %). The introduced approach is attractive due to its applicability in the l
