Embodiment 1

[0037] A serrated Cu 2 MoS 4 The preparation method of nano sheet electricity, photocatalyst, described preparation method comprises the following steps:

[0038] S1 synthesis of Cu 2 O Prebody:

[0039] S1.16. Dissolve 66g of PVP in 100mL deionized water in a water bath at 40°C, and cool the solution with 100mL deionized water after complete dissolution;

[0040] S1.2 Add 2 mmol of copper chloride to the solution, stir to dissolve, then add 20 mL of 2M NaOH solution dropwise, stir and age for 30 minutes, and then add 20 mL of 0.6 M ascorbic acid solution drop by drop after the color of the solution changes from light blue to dark brown;

[0041] S1.3 The above mixed solution was stirred at room temperature for 3 hours, and the stirring was stopped after the color of the solution turned brownish yellow, and the obtained product Cu 2 O was centrifuged three times with deionized water and ethanol respectively and dried at 60°C in a vacuum oven for use;

[0042] S2 synthesiz...

example 2

[0055] Such as Figure 6 described, shows the etch on the jagged Cu 2 MoS 4 The influence of the degree of hydrophilicity of nanosheet powder. The results showed that after etching, the jagged Cu 2 MoS 4 Nanosheets have better hydrophilicity.

example 3

[0057] Such as Figure 7 shown, which shows the effect of etching on the jagged Cu 2 MoS 4 Effect of the specific surface area of ​​the nanosheets. Jagged Cu obtained by etching 2 MoS 4 Nanosheets have a larger specific surface area.

The reaction is efficient, operation is easy, the prepared material is high in stability, and good practical value and application prospects are achieved.

Description

technical field [0001] The invention relates to a highly efficient serrated Cu 2 MoS 4 The invention relates to a method for preparing nanosheet electric and photocatalysts, belonging to the field of inorganic nanometer materials. Background technique [0002] With the development of society and economy, environmental problems have become increasingly serious. In order to fundamentally solve environmental problems, we can start from the following two aspects. First, look for alternative green energy sources to reduce human dependence on non-renewable fossil fuels. Hydrogen is an ideal clean energy. Water splitting is an ideal route to produce hydrogen. Therefore, it is of great significance to develop efficient electrocatalysts for splitting water to produce hydrogen. On the other hand, among all kinds of pollution, water pollution is particularly serious and needs to be solved urgently. [0003] Photocatalytic technology can use "green" sunlight to catalyze and degra...
