Organic Soft Template Method to Arrange Palladium Nanoparticles on Single-Walled Carbon Nanotubes
A facile solution-chemical route was reported to deposit and arrange palladium (Pd) nanoparticles on single-walled carbon nanotubes (SWCNTs) using sodium dodecyl sulfate (SDS) as an organic soft template. SDS was previously formed supramolecular self-assembly on the walls of SWCNTs, which may act as adsorption sites of Pd (II) ions on SWCNTs. The Pd nanoparticles reduced by photo-reduction and formed one-dimensionally ordered arrangement on the surface of SWCNTs with a veriety of helices and tilted angles. Pd nanoparticles have an average size of 3 nm. The structure (distance, helix and tilted angle) of the ordered arrangements were determined by the supramolecular self-assembly of SDS wrapped on SWCNTs.
