Incorporation of copper nanoparticles into the nitrogen‐doped carbon derived from nitrile functionalized ionic liquid as the non‐precious heterogeneous catalytic system toward nitro compounds reduction reaction, a first principle calculation

Abstract

BACKGROUND Today, Nitrogen‐doped carbon materials have gained attention as the robust solid catalyst support for immobilization nanoparticles to expand the heterogeneous catalytic systems due to their chemical and structural stability. Copper nanoparticles, known to be a cost‐effective metal, are one of the most efficient catalyst toward various organic transformations. RESULTS In this paper, the covalent triazine framework mesoporous solid support was successfully fabricated by applying ionic liquid as a nitrogen containing carbon precursor during the ionothermal process with the help of ZnCl2 molten salt at 400 °C. The immobilization of cost‐effective copper nanoparticles on the surface of the new design support was carried out by using Cu (NO3)2 and N2H4. For characterization of the new heterogeneous catalyst, the combination of different physicochemical analyses was done to confirm the successful preparation of catalyst inclusive Fourier transform infrared spectroscopy, X‐ray diffraction, Field emission scanning electron microscopy, N2 adsorption–desorption isotherm, Raman spectroscopy, and thermogravimetric analysis. Besides, DFT (Density functional theory) calculations have been performed to optimize the constructed structures and to calculate their Fermi levels and density of states. CONCLUSION The catalytic capability of this new design catalyst survived in hydrogenation of nitroarenes under aqueous and mild conditions. The result shows that this new heterogeneous mesoporous catalyst has excellent catalytic activity and a high stability towards nitroarenes hydrogenation reaction. Moreover, due to the high stability (thermal and structural), it was recovered and reused up to 7 times without any significant reduction in its catalytic activity. © 2021 Society of Chemical Industry (SCI).

Selenium and nitrogen co‐doped porous carbon immobilized Ag nanoparticles: A practical heterogeneous nanocatalyst for hydrogenation of nitroaromatics

“…Particularly, doping carbon with two or several heteroatoms can further improve the catalytic performance in different organic and electrochemical reactions due to the synergistic effects between various heteroatoms and metal NPs and can significantly inhibit the agglomeration, leaching, and corrosion of metal NPs. [36][37][38] In continuation of our studies on the development of heteroatom-doped carbon materials and their application as supports or heterogeneous catalysts, [39][40][41][42][43][44][45] in this paper, we report the preparation of Ag NPs decorated on selenium and nitrogen co-doped mesoporous carbon (Ag/m-SeNC) by pyrolyzing cheap raw materials of glucose, ammonium chloride (NH 4 Cl), and selenium dioxide (SeO 2 ) as the carbon, nitrogen, and selenium sources and AgNO 3 as a metal precursor. The resultant Se,N-carbon was used as a support for the immobilization of Ag NPs to fabricate a stable nanocatalyst Ag/m-SeNC.…”

Highly selective reduction of nitro compounds catalyzed by MOF‐derived glucose stabilized Fe3O4 under mild conditions

“…To preserve the environment, eliminating pollution and conserving energy are imperative concerns in modern society. 4‐NPh is considered one of the most used substances in the chemical industry, for example, it is employed in dyes, pharmaceuticals, antioxidants, polymers, pesticides, and in the precursors needed in agriculture 16 . On the other hand, organic dyes are widely used in several industries, including in the manufacture of polymer, textile, ceramics, adhesives, nutrition, cosmetics, dyes, and pharmaceuticals 17 .…”

Magnetic selenium and nitrogen dual‐doped mesoporous carbon for immobilization of Pd nanoparticles: The utilitarian heterogeneous catalyst in Heck‐cross coupling reaction

“…Fe 3 O 4 NP is one the most common choice due to its high stability, simple synthesis process, acceptable SSA, high magnetic properties, low-cost and available precursors, and also the eco-friendly aspects. [15][16][17] Continuation of discussions conducted by our research group on the development of new methods for introduction of heterogeneous catalysts and their application in various organic reaction, [18][19][20][21][22][23][24][25][26] in this project, we proposed the new Pd-based magnetic Se/N dual-doped carbon catalyst, denoted as Se-mCN/Fe 3 O 4 /Pd, and its application in C-C bond formation via Heck-Mizoroki cross coupling reaction. In the first step, the Se-mCN support was synthesized by carbonization of the mixture that containing glucose, melamine, NH 4 Cl, and SeO 2 at 550 C. Subsequently, the magnetic support (Se-mCN/ Fe 3 O 4 ) was fabricated in simple way.…”
