Abstract

The invention provides a laminated MoS2-Fe3O4 nano composite material and a preparation method thereof.Molybdenum disulfide powder is added to a layered solution, and layered reaction is performed to form a mixed solution; an antioxidant is added to the mixed solution for oxidation intercalation reaction, and intercalated molybdenum disulfide powder is obtained after filtration and drying; Fe3O4 nano powder and an explosive agent are added to the intercalated molybdenum disulfide powder for explosive reaction, an explosive reaction product is taken out after cooling is performed to reach room temperature, namely the MoS2-Fe3O4 nano composite material is obtained.The sulphophile characteristics of aromatic thioether are utilized to reduce the interlayer van der Waals' force of the raw material molybdenum disulfide powder, and the molybdenum disulfide powder successively undergoes layered stripping in combination with explosive impact.By the adoption of the combination of a sol-gel method and the high-temperature explosive impact, rapid Fe3O4 reduction and MoS2 stripping is completed only through one-step explosion after the intercalated molybdenum disulfide powder is fused with sol, and the laminated MoS2-Fe3O4 nano composite material is successively prepared.

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 -Fe 3 o 4 Nanocomposites and methods for their preparation. Background technique [0002] Graphene-like MoS2 composed of single or few layers of MoS 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 ...
