Two dimensional (2D) molybdenum disulfide (MoS2)/reduced graphene oxide (RGO) nanocomposites are synthesized by a hydrothermal method and served as supports for Pt electrocatalysts towards electrocatalytic methanol oxidation. The Pt nanoclusters with uniform size of 3.41 nm are well-dispersed on the surface of MoS2/RGO sheets. Compare to commercial Pt/C and Pt-MoS2 electrodes, the as-prepared Pt-MoS2/RGO composites display 5.65 and 1.73 times higher electrocatalytic activity of methanol oxidation, respectively. This outstanding electrocatalytic performance evidences 2D MoS2/graphene nanocomposites as promising electrocatalyst supports for the commercialization of fuel cells. (C) 2014 Elsevier B.V.
