preparation example Construction

[0034] see figure 1 , the preparation method of the tungsten disulfide nanomaterial of an embodiment, comprises the following steps:

[0035] S110, mixing the sulfur salt, the tungsten salt and N,N-dimethylformamide uniformly, and then carrying out a solvothermal reaction under the condition of 180° C. to 230° C.

[0036] In one embodiment, the sulfur salt is thioacetamide (TAA).

[0037] In one of the embodiments, the tungsten salt is tungsten hexachloride (WCl 6 ).

[0038] Further, the molar ratio of the tungsten salt to the sulfur salt is 1:5˜1:10. Of course, the molar ratio of tungsten salt to sulfur salt can also be 1:6, 1:7, 1:8 or 1:9.

[0039] Further, the mass volume ratio of the tungsten salt to N,N-dimethylformamide (DMF) is 13.22g / L-39.66g / L. Of course, the mass volume ratio of tungsten salt to N,N-dimethylformamide can also be 26.44g / L.

[0040] In one embodiment, sulfur salt, tungsten salt and N,N-dimethylformamide are placed in a stainless steel reactor l...

Embodiment 1

[0054] Weigh WCl according to the molar ratio of 1:10 6 (0.3966g) and TAA (0.7513g) were placed in a stainless steel reactor with a capacity of 50mL and the inner village was polytetrafluoroethylene, and 30mL of DMF solvent was added to the reactor, and then the reactor was sealed and ultrasonicated for 30min, and then placed at 180 ℃ in a box-type reactor for 24 hours. After cooling down to room temperature naturally, wash with deionized water and absolute ethanol three times respectively, then use vacuum filtration to obtain a filter cake, and place the filter cake in vacuum drying at 60 ℃. Dry in the box for 5 hours to obtain tungsten disulfide nanomaterials.

Embodiment 2

[0056] Weigh WCl according to the molar ratio of 1:10 6 (0.3966g) and TAA (0.7513g) were placed in a stainless steel reactor with a capacity of 50mL and the inner village was p-polyphenol, and 30mL of DMF solvent was added to the reactor, and then the reactor was sealed and ultrasonicated for 30min, and then placed at 200 ℃ in a box-type reactor for 24 hours. After cooling down to room temperature naturally, wash with deionized water and absolute ethanol three times respectively, then use vacuum filtration to obtain a filter cake, and place the filter cake in vacuum drying at 60 ℃. Dry in the box for 5 hours to obtain tungsten disulfide nanomaterials.

Abstract

The invention relates to a tungsten disulfide nanometer material which is of a honeycomb porous structure, a preparation method and application thereof. The tungsten disulfide nanometer material formsa honeycomb porous structure in a nanometer material. The tungsten disulfide nanometer material which is of a honeycomb porous structure is almost not reported in the current public literatures, anda honeycomb porous structure results in a tungsten disulfide nanometer material of a high porosity, thereby increasing the specific surface area of the tungsten disulfide nanometer material. The tungsten disulfide nanometer material can be applied to the technical field of adsorption materials, and has a good effect on removal of the dyes in wastewater.

Description

technical field [0001] The invention relates to the technical field of nanomaterial preparation, in particular to a tungsten disulfide nanomaterial and a preparation method and application thereof.
