Abstract: K1.00080 : DNA-Templated Synthesis of Pt Nanoparticles on Single-Walled Carbon Nanotubes and their Electrocatalytic Properties
Author:
Platinum (Pt) supported on single-walled carbon nanotubes is one of the most
efficient catalysts for both methanol and ethanol electroxidations. However,
there is lack of a facile and environmental method to synthesize Pt
nanoparticles on SWCNTs. In this study, we investigated a novel method to
synthesize Pt nanoparticles on SWCNTs using DNA molecules as dispersing
agent for nanotubes and templates for Pt nanoparticles. Morphology and
structure of Pt nanoparticles and their distributions along SWCNTs as well
as interactions between SWCNTs and DNA molecules were studied with the use
of scanning electron microscopy, transmission electron microscopy, UV-vis
spectroscopy, and X-ray diffraction spectrometer. Electrocatalytic
activities of Pt nanoparticles for methanol and ethanol oxidations were
characterized using cyclic voltammetry and impedance spectroscopy. With this
study, we conclude effects of DNA molecules on synthesis of Pt nanoparticles
on SWCNTs and electrocatalytic activity of Pt nanoparticles supported on
SWCNTs for methanol and ethanol oxidations.
