Embodiment 1

[0026] The preparation of carbon nanofibers, the specific steps are as follows:

Embodiment 2

[0030] SnS 2 / CNFs nanocomposite (0.25-SnS 2 / CNFs), the specific steps are as follows:

[0031] Weigh 87.7 mg (0.25 mol) SnCl 4 ·5H 2 O was dissolved in 20 mL of absolute ethanol and recorded as solution A. Weigh 150 mg (2 mol) CH 3 CSNH 2 Dissolve it in 20 mL of absolute ethanol, and record it as solution B. After mixing the two solutions of A and B evenly, pour them into the liner of a 50mL reactor, and put a piece of carbon nanofiber membrane (2×4cm 2 ) tilted into which the 120 o C for 12 hours, the product obtained was washed three times with deionized water and ethanol successively, and finally at 60 o C for 12 hours to obtain 0.25-SnS2 / CNFs nanocomposites.

Embodiment 3

[0033] SnS 2 / CNFs nanocomposite (0. 5-SnS 2 / CNFs), the specific steps are as follows:

[0034] Weigh 175.3 mg (0.5mol) SnCl 4 ·5H 2 O was dissolved in 20 mL of absolute ethanol and recorded as solution A. Weigh out 150 mg (2 mol) CH 3 CSNH 2 Dissolve it in 20 mL of absolute ethanol, and record it as solution B. After the two solutions of A and B were mixed evenly, they were poured into a 50 mL reactor liner, and a piece of carbon nanofiber membrane (2×4cm 2 ) tilted into which the 120 o C for 12 hours, the product obtained was washed three times with deionized water and ethanol successively, and finally at 60 o C drying for 12 hours to obtain 0.5-SnS 2 / CNFs nanocomposites, SnS 2 The loading mass is 8 mg. attached figure 2 for the above 0.5-SnS 2 SEM images of / CNFs nanocomposites, attached image 3 for the above 0.5-SnS 2 TEM photo of CNFs nanocomposites; as can be seen from the figure, SnS 2 Nanosheets are evenly loaded on the surface of carbon nanofibers....

Abstract

The invention discloses an application of a tin disulfide / carbon nanofiber composite material in degradation of organic pollutants, which comprises the following steps: putting a carbon nanofiber membrane into a precursor solution containing a tin source and a sulfur source, reacting, and drying to obtain the tin disulfide / carbon nanofiber composite material, and putting the tin disulfide / carbon nanofiber composite material into water containing organic pollutants, and then carrying out ultrasonic treatment to remove the organic pollutants in the water. According to the method, different technical ideas are utilized, the purpose of catalytically degrading the organic pollutant bisphenol A through pure SnS2 is achieved, and in the catalytic process, SnS2 can efficiently remove the organic pollutant under ultrasonic stimulation.

Description

technical field [0001] The invention relates to the technical field of nanocomposite materials and piezoelectric catalysis, in particular to a preparation method of a one-dimensional carbon nanofiber and two-dimensional tin disulfide nanosheet composite material and its application in piezoelectric catalysis for removing water body pollutants. Background technique [0002] The rapid development of global industrialization has brought severe environmental pollution and resource shortage problems. In particular, the accumulation of some toxic organic compounds has led to the decline of water, air and soil quality. The dangerous properties of these toxic compounds have seriously affected the ecosystem and endangered human health. The storage and utilization of solar energy is considered to be an effective strategy to alleviate the current environmental pollution and resource shortage. Semiconductor photocatalysis generally involves three basic steps: (1) absorption of photons ...
