Graphene has been successfully modified with palladium nanoparticles in a facile manner by reducing palladium acetate [Pd(OAc)2] in the present of sodium dodecyl sulfate (SDS), which is used as both surfactant and the reducing agent. The palladium nanoparticle-graphene hybrids (Pd-graphene hybrids) are characterized by high-resolution transmission electron microscopy, atomic force microscopy, Raman...
An argon glow discharge plasma was used for the reduction of carbon black-supported platinum (Pt) catalysts with high loading of the metal. High dispersion of the Pt on the carbon black was obtained by such plasma reduction, operated at ambient temperature. The average particle size was 1.43nm with 20wt% platinum loading, whereas it was 1.50nm with 40wt% platinum loading. An increase in the loaded...
