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.
