AbstractMolybdenum disulfide hybridized with graphene nanoribbon (MoS2/GNR) was prepared by mild method. MoS2/GNR hybrids interlace loosely into a three-dimension structure. GNR hybridization can improve the dispersity of MoS2, reduce the grain size of MoS2 to 3–6 nm, increase the specific surface area, and broaden the interlamellar spacing of MoS2 (002) plane to 0.67–0.73 nm, which facilitates the transportation of Li+ ions for lithium-ion battery. MoS2/GNR hybrids have better cyclic durability, higher specific discharge capacity, and superior rate performance than MoS2. The electrocatalytic activity in hydrogen evolution reaction shows that MoS2/GNR hybrids have the lower overpotential and the larger current density with a negligible current loss after 2000 cycles. Hybridizing with GNRs enhances both the lithium-ion electrochemical storage and the electrocatalytic activity of MoS2. Graphical abstractMoS2/GNR hybrid prepared by a mild method is interlaced loosely into a three-dimension structure. Superior electrochemical performances of MoS2/GNR hybrids than MoS2 have been highlighted for the potential application for long- term durability energy-storage devices and HER electrocatalytic materials.
