Preparation of Pt nanoparticle-adsorbed Carbon Nanotubes Using Room Temperature Ionic Liquid and Their Use as Electrocatalyst for Oxygen Reduction

摘要

Pt nanoparticles dispersed in room temperature ionic liquid (RTIL) can easily be prepared by metal-sputtering onto RTIL. When the prepared Pt nanoparticles-dispersed RTIL is put on a glassy carbon (GC) plate or mixed with single wall carbon nanotubes (SWCNTs) while being heated, adsorption of Pt nanoparticles on the carbon surfaces is induced. Both resulting Pt nanoparticles-adsorbed GC and SWCNT exhibit distinct electrocatalytic activity toward oxygen reduction reaction.
