Problems solved by technology

Although this method has obtained a graphene-bismuth molybdate composite material with high photocatalytic activity, this method needs to oxidize and then reduce graphite, the preparation process is complicated, the efficiency is low, and the photocatalytic activity of the composite material is not high. To achieve the required high efficiency, it is necessary to further explore other means to improve its photocatalytic activity

Abstract

The invention provides a preparation method of layered MoS2-Bi2MoO6 nanocomposite.Molybdenum disulfide powder is added into a layering solution to be subjected to a layering reaction, and a mixed solution is formed; an oxidizing agent is added into the mixed solution so that an oxidizing intercalating reaction can be performed, and intercalated molybdenum disulfide powder is obtained after filtering and drying; the molybdenum disulfide powder is dispersed in distilled water, Bi2MoO6 powder is added, stirring and mixing are performed, and MoS2-Bi2MoO6 mixed powder is obtained after filtering and drying; the MoS2-Bi2MoO6 mixed powder is mixed with an exploding agent, an exploding reaction is performed, and an exploding reaction product is taken out after temperature is lowered to room temperature; the layered MoS2-Bi2MoO6 nanocomposite is obtained.By means of the sulphophile characteristic of aromatic sulfur ether, the interlayer Van der waals force of the molybdenum disulfide raw material powder is reduced, and intercalation stripping is performed on the molybdenum disulfide raw material powder by means of exploding impact.The method is adopted for preparing the layered MoS2-Bi2MoO6 nanocomposite, operation is easy, no complicated equipment is needed, the preparation efficiency is high, and the yield is high.

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 -Bi 2 MoO 6 Preparation methods of nanocomposites. 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. As an important class of two-dimensional layered nanomaterials, single-layer or few-layer molybdenum disulfide is widely used in many fields such as lubricants, catalysis, energy storage, and composite materials due to its unique "sandwich sandwich" layered structure. Compared with the zero-energy bandgap of graphene, graphene-like molybdenum disulfide has an adjustable energy bandgap, which has a brighter prospect in the field of optoelectronic ...
