The PVP-protected Pt-Ru alloys were firstly prepared using gamma-irradiation at room temperature. The Pt-Ru alloys were successfully dispersed on various carbons such as Vulcan XC-71, Ketjen-300, Ketjen-600, single-walled carbon nanotubes (SWCNTs), and multi-walled carbon nanotubes (MWCNTs) as supporting materials usinggamma-irradiation at room temperature for the direct methanol fuel cell and CO2 hydrogenation. The Pt-Ru/C catalysts were characterized by TEM, XRD, EDS and porosimeter. The TEM images and XRD data demonstrate that the well-dispersed Ag (~ 5nm) was dispersed onto the surface of carbons. The catalyst examination for methanol oxidation and CO2 hydrogenation was performed. |
