Abstract

Mesoporous materials have been the subject of intense research regarding their unique structural and textural properties and successful applications in various fields.

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

“…To reduce costs and replace rare metals, researchers are exploring the potential of earth-abundant metals (EAMs) such as Co, Mn, Fe, Zn, Mo, and Ni for acceptorless dehydrogenative reactions. 18 In the realm of these reactions, catalysts assume a pivotal role, prompting endeavors toward the creation of recyclable, efficient, and environmentally friendly catalysts that align with the tenets of green chemistry. Nanocomposites (NCs) are composite materials containing at least one nanoscale component.…”

Pd NPs decorated on crosslinked sodium alginate modified iron-based metal–organic framework Fe(BTC) as a green multifunctional catalyst for the oxidative amidation

“…Metal-organic frameworks (MOFs) are nanoscale materials that have shown hope-giving results in various catalytic applications due to their strong Brønsted acidity, high thermal stability, high surface area, and numerous active sites. MOFs are composed of metal ions or clusters and custom-designed organic ligands, offering a vast array of structural motifs and SBUs that can be incorporated into the materials [17][18][19]. These features make MOFs a promising candidate for further in the field of material science and related applications [20,21].…”

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

“…Regarding the growing interest of organic chemists in nanocomposites, several studies have been conducted on these materials due to the unique surface and physical properties of these heterogeneous catalysts in different organic reactions. [26][27][28][29][30][31] Nowadays, magnetic nanoparticles, which are one of the most inuential factors in the nanomaterial family, have been extensively employed in different sciences, consisting of drug shipping, sickness recognition, water desalination, and chemical catalysis. 3,31 Among magnetic nanoparticles, nanophase spinel ferrites with superparamagnetic behavior are presently utilized in drug transport, microwave devices, catalytic activity, and magnetic imaging.…”
