Facile synthesis of AgNPs/MoS2 nanocomposite with excellent electrochemical properties

Two-dimensional (2D) nanomaterials, such as boron nitride (BN), molybdenum disulfide (MOS2), have attracted increasing research interest in the past few years because of the unique properties of graphene. The monolayer and few-layers MOS2 nanosheets were obtained by combined low-energy ball milling and sonication. A self-assembly method was then applied to load silver nanoparticles (AgNPs) onto the two-dimensional MOS2 nanosheets for the fabrication of OD/2D multifunctional nanocomposites with an enhanced Raman affect. The AgNPs are uniformly dispersed on the MOS2 nanosheets and the particle size of the AgNPs is about 4 nm. The AgNPs/MOS2 nanocomposites are characterized by cyclic voltammetry, showing excellent electrochemical performances. (C) 2015 Elsevier B.V. All rights reserved.
