Abstract

A synthesis method of a MoS2 nano-structure material is carried out with MoO2 as a precursor and L-cysteine as a sulfurizing agent under a hydrothermal condition. The synthesis method includes the steps of: (1) dissolving 5 parts by mass of MoO2 in 2 parts by mass of n-hexanol; (2) adding 1-5 parts by mass of L-cysteine to the solution prepared in the step (1), wherein the solution contains 8 parts by mass of the MoO2 and all the mass part values are integers; (3) uniformly stirring the solution in the step (2); (4) pouring the solution in the step (3) into a stainless steel hydrothermal reaction kettle to perform a reaction; (5) centrifuging a reaction product in the step (4) for 20-30 min; (6) performing ethanol ultrasonic cleaning to the centrifuged reaction product in the step (5); and (7) drying the cleaned product in the step (6).

Description

technical field [0001] The invention belongs to the technical field of inorganic advanced materials, and specifically relates to a MoS with regular spherical shape and uniform particle size 2 Methods for the synthesis of nanostructured materials. Background technique [0002] With the gradual depletion of traditional fossil, coal and other energy sources and the increasingly prominent environmental pollution problems, it is imminent to find green and sustainable energy sources. As an ideal energy carrier, hydrogen has the advantages of greenness, environmental protection, high energy density and wide sources, especially in the process of energy conversion, the final product is water, and no pollutants such as nitrides and sulfides are produced. In addition, hydrogen not only It can be used as a clean fuel, and also has important uses in chemical industry, petroleum and metallurgy, such as industrial ammonia synthesis. Therefore, exploring efficient and energy-saving hydrog...
