Pt-based nanomaterials are considered as the most effective electrocatalysts for direct methanol fuel cells (DMFC)[1].Herein,graphene supported binary PtPd (PtPd-G) and ternary PtPdRu (PtPdRu-G) nanocatalysts were fabricated by facile one-pot hydrothermal strategy using triblock pluronic copolymer P123 as both reducer and stabilizer[2].The co-reduction of metal precursor and graphene oxide results in the in-suit loading mode.
