Abstract: | 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 O_2 plasma to transform into oxide carbon nanotubes(O-CNTs),and then it was mixed with the precursors(the mixture of H_2 PtCl_6and PdCl_6).After that,the O-CNTs and the precursors were simultaneously treated by H_2 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. |
