Palladium nanoparticles supported onto ionic carbon nanotubes as robust recyclable catalysts in an ionic liquid

Abstract

Palladium nanoparticles have been deposited onto imidazolium bromide-functionalized ionic MWCNTs through hydrogen reduction of Na2PdCl4 in water without aid of surfactants under extremely mild conditions, and combined with an ionic liquid to create a new recyclable ionic liquid-based catalytic system allowing up to 50 times recycling.

Effective functionalization of carbon nanotubes for bisphenol F epoxy matrix composites

“…The imidazole functionalized CNTs were prepared according to our previously reported procedures 38,39 . The carboxylic acid group was converted to acid chloride by treatment with SOCl 2 (reflux for 24 hours).…”

“…The reason may be explained as follows: ionic liquid served as the high effective conductive pathway and reduced contact resistance between the well-dispersed CNTs. Therefore π-electrons of CNTs can easily get across the insulating polymer resin by CNTs and ionic liquid conductive matrix 38,39 . Moreover with the increase of CNT percentage, the CNTs-IL/epoxy system can achieve a conductivity of 8.38×10…”

“…Further, Ag, Cu, Pt and Ag@Au NPs were also successfully synthesized in situ on the surface of CNT/DEN with a great control on its particle size. The Pd NPs were also deposited on the surface of MWCNTs which were initially functionalized with thiol [56], benzenesulfonic [57] and ionic liquid functionalized MWCNTs [58]. Banerjee et.al.…”
