It is reported that the highly dispersed Pt nanoparticles on carbon nanotubes can be synthesized under mild conditions by in situ plasma treatment.The carbon nanotube was pretreated by O2 plasma to transform into oxide carbon nanotubes(O-CNTs),and then it was mixed with the precursors(the mixture of H2 PtCl6and PdCl6).After that,the O-CNTs and the precursors were simultaneously treated by H2 plasma.The precursors were transformed into Pt-Pd nanoparticles(NPs)and the O-CNTs transformed into CNT.The synthesized CNT-based Pt-Pd nanoparticles were characterized by scanning electron microscopy,transmission electron microscopy,X-ray diffraction and X-ray photoelectron spectroscopy.All the analysis showed that the Pt-Pd nanoparticles were deposited on CNT as a form of face-centered cubical structure.
