High dispersion and electrocatalytic properties of Pt nanoparticles on SWNT bundles

Open access
Guo, Dao-Jun, Li, Hu-Lin·2004·Journal of Electroanalytical Chemistry

Abstract

Platinum (Pt) nanoparticles were electrochemically dispersed on single-walled carbon nanotube (SWNT) bundles by electro-reduction of the Pt(IV) complex formed on the SWNT surface. The structure and elemental composition of the resulting Pt/SWNT composite were characterized by transmission electron micrograph (TEM), X-ray diffraction (XRD) and energy dispersive X-ray spectroscopy (EDS). The electrocatalytic properties of the Pt/SWNT electrode for methanol oxidation have been investigated by cycle voltammetry (CV). A high electrocatalytic activity and excellent stability of the Pt/SWNT electrode can be observed. This may be attributed to the high dispersion of platinum nanoparticles and the particular properties of the SWNT supports. The results imply that the Pt/SWNT composite has good potential applications in fuel cells.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
