dc.description.abstract | The immobilization of platinum (Pt) nanoparticls on the surface of multi-walled carbon nanotubes (MWCNTs) was carried out by polyol process, with hydroxyl (-OH), carboxyl (-COOH) and carbonyl (C=O) groups on the MWCNTs surfaces by acid oxidation treatment serving to bind Pt nanoparticles. The resulting composite nanostructures were characterized through transmission electron microscopy and X-ray diffractmeter. The Pt nanoparticles that formed on the surfaces of the MWCNTs (Pt/MWCNTs) had an average diameter of ca. 4 nm. The aggregation and size of Pt nanoparticles on the surface of MWCNTs were influenced by the concentration of polyvinylpyrrolidone (PVP), the different molecular weight of PVP and the molar ratio of the reducing agent to Pt ions in the reaction medium. In addition, the concentration of Pt source (H2PtCl6) had profound influence on the immobilization of Pt nanoparticles on the surface of MWCNTs. When PVP as a stabilizer was in the solution, the coverage and number of Pt nanoparticles were increased upon increasing the concentration of Pt source. However, the degree of aggregation of Pt nanoparticles on the surface of MWCNTs was also increased. | - |
