Adsorption of methylene blue on cashew nut shell based carbons activated with zinc chloride: The role of surface and structural parameters

The application of the magnetic nanocatalysts is a rapidly growing field for the development of sustainable and green processes Magnetic separation not only avoids the need for catalyst filtration or centrifugation after completion of the reaction, but also provides practical techniques for recovering these catalysts Multicomponent reactions are recognized as very powerful tools in synthetic organic and medicinal chemistry for the synthesis of the complex products in a single step from simple starting materials The combination of magnetic nanocatalysts and multicomponent reactions will become an emerging strategic research area and is an ideal blend for the development of sustainable methods in green synthetic chemistry This review focuses on the synthesis and application of magnetic nanocatalysts as novel task-specific catalysts for multicomponent reactions in recent years

Magnetic nanocatalysts: Synthesis and application in multicomponent reactions

A review on the field patents and recent developments over the application of metal organic frameworks (MOFs) in supercapacitors

In the current paper, we successfully developed and used metal-organic frameworks (MOFs) based on MIL-101(Cr)-NH2 with phosphorus acid functional groups MIL-101(Cr)-N(CH2PO3H2)2. The synthesized metal-organic frameworks (MOFs) as a multi-functional heterogeneous and nanoporous catalyst were used for the synthesis of N-amino-2-pyridone and pyrano [2,3-c]pyrazole derivatives via reaction of ethyl cyanoacetate or ethyl acetoacetate, hydrazine hydrate, malononitrile, and various aldehydes. The final step of the reaction mechanism was preceded by a cooperative vinylogous anomeric-based oxidation. Recycle and reusability of the described catalyst MIL-101(Cr)-N(CH2PO3H2)2 were also investigated.

Metal–organic frameworks: advanced tools for multicomponent reactions

A convenient method for the synthesis of pyrido[2,3-d]pyrimidines by using the novel nano-magnetic silica-bonded S-sulfonic acid[Fe3O4@SiO2@(CH2)3S–SO3H] as an efficient and recyclable catalyst under neat conditions is described. The major advantages of the present methodology are high yield, short reaction time, and reusability of the catalyst. Furthermore, the nano-magnetic silica-bonded S-sulfonic acid was fully characterized by using various techniques such as FT-IR, TG/DTG, DTA, EDX, μXRF, XRD, HRTEM, SEM, SEM elemental mapping, XPS, and N2 physisorption. The results obtained from this research support the idea of rational design, synthesis, and applications of task-specific and reusable catalysts for the preparation of various polynitrogenated heterocyclic compounds containing 1,4-dihydropyridine moieties.

Preparation of nanostructured carbon covered sand for removal of methyl violet from water

The aim of this work is the study of the reduction of dioctylphthalate (DOP) plasticizer migration from polyurethane (PU) to ethylene propylene diene monomer (EPDM) substrate by using a polyurethane-based liner containing carboxylated carbon nanotube (CNT). Dispersion of CNT in PU was well performed using DMAc solvent and sonication. Dispersion rate was evaluated by FESEM analysis. In order to study mechanical properties of the synthesized liners, tensile strength, elongation at break, and hardness analysis were investigated. The results showed that by increasing CNT content, tensile strength and hardness have not significantly changed, whereas the percentage of elongation at break has been increased. Swelling of the samples was studied by using acetone solvent and the results showed that the swelling rate increased slightly with increasing the CNT content. Migration of plasticizer was assessed by measurement of DOP content in the liner and EPDM by HPLC analysis. Based on the obtained results using a liner containing CNT as an inhibitor could prevent DOP migration.
