摘要:The carbon nanotubes (CNTs) without modification for any functional group are used for the formation of CNTs/Pt nanocomposites in the presence of 1-butyl-3-methylimidazolium chloride ([BMIM]Cl) ionic liquid (IL) at a mild condition. The effects of platinum salt and [BMIM]Cl concentrations on the morphologies of final products are investigated. The as-prepared products are characterized by transmission electron microscopy, powder X-ray diffraction, and cyclic voltammetry. It shows that the as-prepared CNTs/Pt nanocomposites have a good dispersion of Pt particles with tunable size by controlling the concentration of [BMIM]Cl. The Pt particle size of the synthesized CNTs/Pt nanocomposites could be as small as 7 +/- 2 nm. The possible formation mechanism of the as-prepared nanocomposites is proposed based on the p-p interaction between the IL and the CNT. The electrochemical response of the synthesized CNTs/Pt nanocomposites to K-3(FeCN)(6) is studied by cyclic voltammetry measurements, which demonstrates the response increases with the decrease of the Pt particle size. Moreover, the electroactivity for methanol oxidation using the synthesized CNTs/Pt nanocomposites with Pt particle size of 7 +/- 2 nm shows that the asprepared CNTs/Pt nanocomposites have an improved catalytic performance.
