Insoluble dendrimer-grafted poly(vinylimidazole) microbeads stabilized with mono/bimetallic nanoparticle catalysts for effective degradation of malachite green

Abstract

Six types of heterogeneous nanoparticle catalysts viz., insoluble Poly-VIm beads grafted with D(G2) & D(G3) PPI dendrimers stabilized/immobilized with AuNPs/AuPdNPs were prepared by varying the cross-linking load as 2% (LC) and 10% (HC) and demonstrated the same as superior catalysts for effective reduction of Malachite Green.

Dendritic fibrous nanosilica-supported dendritic IL/Ru(ii) as photocatalysts for the dicarbofunctionalization of styrenes with carbon dioxide and amines

“…64,65 The immobilization of dendrimer catalysts on support materials is a new eld that has attracted the attention of many chemists due to the facile recoverability. [66][67][68] ILs have a special place in green chemistry because of their unique attributes such as light vapor pressure and slight ignition. The adaptability of the anatomy and characteristics is a signicant feature of ILs.…”

Metal‐Free Catalytic Reduction of 4‐Nitrophenol by MOFs‐Derived N‐Doped Carbon

“…P‐nitrophenol, as a common intermediate of pharmaceuticals, dyes, pesticide, oil refineries and so on, widely exist in industrial effluents and agricultural waste‐water . It is one of the most toxic and refractory pollutants because of the huge damage in the central nervous system, kidney, liver and blood of humans even at low concentration .…”

Core–Shell Nanostructured Fe3O4–Poly(styrene-co-vinylbenzyl chloride) Grafted PPI Dendrimers Stabilized with AuNPs/PdNPs for Efficient Nuclease Activity

“…Further, to enhance the stability and dispersability of magnetic nanocomposite, it is essential to identify the relevant functional polymer coated with Fe 3 O 4 NPs and the relevant shell or functional polymer. More specifically, dendrimers grown onto the solid matrix including poly(styrene) bead, 31 magnetic NPs, 32 carbon black, 33 and silica 34 have been the recently reported techniques for the design of innovative dendritic-based catalysts. Dendrimers are an attractive symmetrical supramolecules having excellent efficiency to generate metal NPs via encapsulation and stabilization processes.…”
