摘要：
Platinum/reduced graphene oxide-molybdenum disulfide composite (Pt/rGO-MoS2) is synthesized by employing H-2-plasma technique. The morphology, structure and component of Pt/rGO-MoS2 are investi-gated. Compared with Pt/rGO or Pt/MoS2, the as-prepared Pt/rGO-MoS2 catalyst exhibits large electro-chemical active area (104.3 m(2) g(-1)), high current density (737.8 mA mg(-1)) for methanol oxidation reaction (MOR) and long-term stability. These improvements are attributed to the rGO-MoS2 support that improves the dispersion of Pt NPs and offers sufficient electronic conductive channels. With these excel-lent electrochemical performances, this work may therefore offer a promising electrocatalyst for large-scale commercial application of fuel cells. (C) 2020 Elsevier B.V.
