Functionalization of Carbon Nanotubes by an Ionic‐Liquid Polymer: Dispersion of Pt and PtRu Nanoparticles on Carbon Nanotubes and Their Electrocatalytic Oxidation of Methanol

Abstract

Small beginnings: Metal nanoparticle/CNT nanohybrids are synthesized from carbon nanotubes (CNTs) functionalized with an ionic-liquid polymer. The Pt and PtRu nanoparticles with narrow size distribution (average diameter: (1.3+/-0.4) nm for PtRu, (1.9+/-0.5) nm for Pt) are dispersed uniformly on the CNTs (see images) and show good performance in methanol electrooxidation.

Effective functionalization of carbon nanotubes for bisphenol F epoxy matrix composites

“…(%) but still higher than that of the pristine epoxy resin. This was due to the existence of the defects could be used instead to fix and repair those defects partially to increase the conductivity of CNT itself 50 . This gives rise for future investigation of a new possible electro-path under potential applied.…”

Nanoparticle Preparation in Room-Temperature Ionic Liquid under Vacuum Condition

“…12). Several research groups point out that RTIL improves a catalytic ability for ORR (Li et al, 2009;Wang et al, 2008;Wu et al, 2009;Yu et al, 2008;Zhao et al, 2006). We have investigated ORR using a RTIL-modified Pt-GCE.…”

Supramolecular Structures in the Presence of Ionic Liquids

“…Supramolecular gelation in IL could be used in many fields, such as actuators, polymer electrolytes, membranes, or gate dielectrics for organic transistors. The structures and characteristics of nanohybrids or nanocomposites or self-organized nanotubes can be changed by the assistant of ILs (Gopalan et al, 2009;Li et al, 2009a;Paramasivam et al, 2008;Park et al, 2009b;Wu et al, 2009a). There are two aspects about effects of ILs on these supermolecules, which influence the system individually or jointly.…”

“…There are two aspects about effects of ILs on these supermolecules, which influence the system individually or jointly. One is that ILs affect the supermolecules because of the anions and cations of ILs and aromatic structures, which can result in electrostatic interactions, cation-π and/or π-π stacking interactions (Gopalan et al, 2009;Park et al, 2009a;Park et al, 2009b;Wu et al, 2009a;Zhang et al, 2009). The other is that self-assemby of ILs influence the supermolecules (Gutel et al, 2007;Ma et al, 2009;).…”
