Problems solved by technology

Because nanoparticles are easy to agglomerate during the preparation process, the morphology of the molybdenum disulfide nano-core-shell nanostructure obtained by the prior art is not easy to control, and the prior art process is complicated, which affects its scale in the fields of tribology, photochemistry, catalysis, etc. application
However, there are few relevant literature reports on molybdenum disulfide flower-shaped nanorods, and the cost is high and the process is complicated.

Embodiment 1

[0020] Dissolve 0.4g benzyltriethylammonium chloride and 0.42g Pluronic F-127 in 60mL of deionized water, then add 0.88g sodium molybdate, 1.40g sodium sulfide, and 0.6g glucose, after completely dissolving , and then adjust the pH value to about 6 with 2mol / L HCl; after stirring for 30min, transfer the mixture to a 100mL stainless steel reaction kettle, place it in a vacuum oven at 160°C for 24h, and cool to room temperature. After the reaction product was separated by centrifugation, it was washed repeatedly with deionized water and absolute ethanol, and finally dried at 60° C. for 12 hours under vacuum to obtain a gray-black powder product, namely molybdenum disulfide flower-like nanorods.

Abstract

The invention provides a preparation method of flower-shaped molybdenum disulfide nano-rods. The preparation method comprises steps as follows: a surfactant is dissolved in water firstly, sodium molybdate, sodium sulfide and glucose are added and stirred, and the pH value of a solution is regulated to 6-8; the solution is transferred to a reaction kettle for sealing and is cooled to the room temperature after a thermostatic reaction, and a reaction product is obtained; finally, the reaction product is separated, washed and dried, and the flower-shaped molybdenum disulfide nano-rods are obtained. The preparation method is low in cost, the production technology is simple and easy to control, the product yield is high, and the preparation method is suitable for large-scale industrial production.

Description

technical field [0001] The invention belongs to the technical field of nanometer materials, and in particular relates to a preparation method of molybdenum disulfide flower-like nanorods. Background technique [0002] Transition metal sulfides are a class of two-dimensional layered compounds with excellent physical and chemical properties due to their unique structures, and are used in many technologies such as tribology, drug delivery carriers, photonic crystals, catalysts and energy storage, and high-performance composite materials. fields have important applications. Among them, molybdenum disulfide has the characteristics of a special hexagonal layered structure. Its layers are combined by strong chemical bonds, and the layers are combined by weak van der Waals forces. Weaker, making the shear resistance between layers very weak. Therefore, molybdenum disulfide has many unique properties and is widely used in solid lubrication, hydrogen storage materials, lithium stora...
