Abstract

The present invention provides a layered MoS 2 ‑Ni nanocomposite preparation method, adding molybdenum disulfide powder into the layered solution for layering reaction to form a mixed solution; adding an oxidant to the mixed solution for oxidation intercalation reaction, filtering and drying to obtain intercalated molybdenum disulfide powder Dissolve nickel acetylacetonate in tetrahydrofuran, add intercalated molybdenum disulfide powder, stir and mix for reaction, centrifuge, wash, and dry to obtain MoS 2 ‑Ni mixed powder; MoS 2 / Ni mixed powder is mixed with explosive agent for explosive reaction, and after cooling to room temperature, the explosive reaction product is taken out to obtain layered MoS 2 ‑Ni nanocomposites. The product prepared by the present invention is a composite nanomaterial of layered molybdenum disulfide and Ni nanoparticles with high carrier mobility, and the Ni nanoparticles are evenly attached to the single-layer molybdenum disulfide sheet, which improves its catalytic hydrogenation And lubricating properties, greatly expanding the scope of application of molybdenum disulfide.

Description

technical field [0001] The invention belongs to the technical field of metal molybdenum, relates to molybdenum disulfide composite materials, and in particular to a layered MoS 2 - Preparation method of Ni nanocomposite material. Background technique [0002] Graphene-like MoS2 composed of single or few layers of MoS2 2 ) is a new type of two-dimensional (2D) layered compound with graphene-like structure and properties. In recent years, it has become an emerging research hotspot due to its unique physical and chemical properties. Graphene-like molybdenum disulfide is a two-dimensional crystal material with a "sandwich sandwich" layered structure composed of a hexagonal single-layer or multi-layer molybdenum disulfide. The single-layer molybdenum disulfide is composed of three atomic layers. The layer is a molybdenum atomic layer, and the upper and lower layers are sulfur atomic layers. The molybdenum atomic layer is sandwiched by two sulfur atomic layers to form a "sandwic...
