Cu(ii) immobilized on poly(guanidine-sulfonamide)-functionalized Bentonite@MgFe₂O₄: a novel magnetic nanocatalyst for the synthesis of 1,4-dihydropyrano[2,3-c]pyrazole

Abstract

In this paper, we aim at synthesizing a new nanocomposite material in which bentonite acts as a nucleation site for MgFe2O4 nanoparticles precipitation in the attendance of an external magnetic field (MgFe2O4@Bentonite).

Synthesis of benzothiazoles using an iron-anchored polysulfonamide modified layered double oxide/sodium alginate nanocomposite

“…These nanocomposites involve the integration of one or more organic polymer matrices with one or more nanofillers, which may belong to either the organic or inorganic category. 26–32 Employing an inorganic filler within an organic polymeric matrix, polymer-inorganic filler nanocomposites (PIF-NCs) have gained prominence for their exceptional properties. These materials, distinguished by their outstanding characteristics, are widely applied in various fields such as adsorption, separation, membrane filtration, catalysis, drug delivery, and energy storage.…”

A sustainable protocol for selective alcohols oxidation using a novel iron-based metal organic framework (MOF-BASU1)

“…Recently, various homogeneous catalysts have played an important role owing to their efficiency and all-purpose impact on the many catalytic reactions. 7–9 However, despite the high efficiency of homogeneous catalysts, all these reactions suffer from poor catalyst recovery. The benefits of catalyst recovery include the economic and environmentally friendly concept of special transition metals; however, the key challenges are yet to be resolved.…”
