Embodiment 1

[0038] A Hierarchical MoS 2 / Cu 2 S composite material, its preparation method comprises the steps:

[0039] Add 0.4g of sodium molybdate, 0.4g of thioacetamide, and 0.04g of copper sulfate pentahydrate into a mixed solution of 20mL of ethylenediamine, 40mL of water and 20mL of ethanol, stir and mix evenly (the stirring temperature is 25°C, and the stirring rate is 700r / min), then put the resulting mixture in a reaction kettle, seal it and heat it to 200°C for constant temperature crystallization reaction (hydrothermal reaction). After reacting for 24 hours, carry out suction filtration, washing, and then dry at 60°C to score hierarchical structure MoS 2 / Cu 2 S composites.

[0040] The product obtained in this example is determined to be the same as the MoS of hexagonal crystal form through X-ray diffraction analysis. 2 and Cu 2 The S phase matches, and the crystallinity is good, and its X-ray diffraction pattern is shown in figure 2 . Scanning electron microscopy re...

[0044] A Hierarchical MoS 2 / Cu 2 S composite material, its preparation method comprises the steps:

[0045] Add 0.4g of sodium molybdate, 0.8g of thioacetamide, and 0.08g of copper sulfate pentahydrate into a mixed solution of 20mL of ethylenediamine, 40mL of water and 20mL of ethanol, stir and mix evenly (the stirring temperature is 25°C, and the stirring rate is 700r / min), then put the resulting mixture in a reaction kettle, seal it and heat it to 220°C for constant temperature crystallization reaction (hydrothermal reaction), after 48 hours of reaction, carry out suction filtration, washing, and then dry at 60°C to score hierarchical structure MoS 2 / Cu 2 S composites.

[0046] The product obtained in this example is determined by X-ray diffraction analysis to be consistent with hexagonal MoS 2 and Cu 2 The S phase matches, and the crystallinity is good, and its X-ray diffraction pattern is shown in Figure 6 . Scanning electron microscopy results showed that ( F...

Abstract

The invention discloses a hierarchy MoS2 / Cu2S composite material. The hierarchy MoS2 / Cu2S composite material is a micro-nano sphere with a flower-like structure formed by assembling MoS2 nanosheets and Cu2S nanosheets and is obtained by carrying out hydrothermal reaction on a molybdenum source, a sulfur source, a copper source and a reducing agent which serve as raw materials. The MoS2 / Cu2S composite material disclosed by the invention is prepared by using a hydrothermal method, and has the advantages of wide source of the related raw materials, low cost, simple and feasible technology and high yield; the difficult point that MoS2 is difficultly compounded with other materials at present can be solved; besides, the problem of low conductivity of the MoS2 in the catalytic reaction process also can be solved; the obtained composite material shows excellent photocatalytic performance and excellent electrocatalytic performance and is suitable for being popularized and applied.

Description

technical field [0001] The invention belongs to the technical field of inorganic materials, in particular to a MoS with hierarchical structure 2 / Cu 2 S composite materials and their preparation methods. Background technique [0002] With the development of society, energy and environmental issues have become increasingly severe. The preparation of new clean energy to replace non-renewable energy has become a hot spot of attention. Among them, electrocatalytic hydrogen production has the advantages of non-toxicity, cheap and easy-to-obtain materials, and little secondary pollution. It is a very promising technology. [0003] MoS 2 As a kind of electrocatalytic material with nanoscale layered structure, it has attracted the attention of scientists because of its unique electrical properties and excellent mechanical properties. This type of compound is a sandwich structure in which metal atomic layers are arranged in two sulfur atomic sheets, and the sulfur atomic sheets i...
