The third step: 1T/ 2H-MoS growth on carbon fiber cloth by hydrothermal method2
A piece of activated carbon fiber cloth was dispersed in the solution, and the mixture was then transferred to a 50mL autoclave. The autoclave was sealed and kept at 180 ℃ for 24 h. And when the high-pressure kettle is naturally cooled, collecting the product, respectively washing the product for a plurality of times by using distilled water and ethanol, and then drying the product in vacuum to obtain the carbon fiber cloth composite material.
The fourth step: three-dimensional hollow conical structure prepared from carbon fiber cloth composite material
1T/2H-MoS grows on one piece2The back of the carbon fiber cloth is compounded with non-woven fabric, and then the carbon fiber cloth is folded into a hollow cone shape shown in fig. 8, when the carbon fiber cloth is folded, the composite material faces outwards, and the non-woven fabric faces inwards; and then mechanically supporting by using a dehydration cotton stick to form an umbrella shape shown in figure 8, inserting the dehydration cotton stick into polyethylene foam plastic to prepare a light absorption body, then placing the light absorption body into a polytetrafluoroethylene container containing seawater, placing the polytetrafluoroethylene container on a balance, irradiating by using a simulated light source, recording the mass change at different moments, and calculating the water evaporation rate so as to obtain the photo-thermal conversion efficiency. In the whole process, the temperature of the molten iron is controlled,the polyethylene foam is used for heat insulation to reduce heat loss, and the non-woven fabric with good hydrophilicity is used as a water delivery channel to ensure high-efficiency water supply through capillary force.
Tests prove that the solar absorptivity of the photo-thermal material in the embodiment reaches 98 percent, and the water evaporation rate reaches 1.61kg m-2h-1About 3.69 times of pure seawater, and the photo-thermal conversion rate reaches 97%.
Example two
The second embodiment is different from the first embodiment in that: and (3) only ultrasonically cleaning the carbon fiber cloth by using absolute ethyl alcohol and deionized water for 5min, without carrying out activation treatment and hydrothermal experiments, and carrying out performance test after the rest processes and parameters are the same as those of the first embodiment.
Tests prove that the solar absorptivity of the secondary light absorption material in the embodiment is 88 percent, and the water evaporation rate reaches 1.22kg m-2h-1The photothermal conversion rate was 78%.
Comparing the test data of the first and second examples, the carbon fiber cloth composite material prepared by using the activated carbon fiber cloth as the matrix is found to have solar absorptivity or water evaporation rate far superior to that of the carbon fiber cloth test result without activation, which shows that the activation of the carbon fiber matrix before the preparation of the composite material is necessary.
EXAMPLE III
The third embodiment is different from the first embodiment in that: and (3) ultrasonically cleaning the carbon fiber cloth for 5min by using absolute ethyl alcohol and deionized water respectively, then annealing for 2h in a muffle furnace at 350 ℃ to activate the carbon fiber cloth, sealing the reaction kettle for 24h at 160 ℃, keeping the rest processes and parameters the same as those of the first embodiment, and then carrying out performance test.
Tests show that the solar absorptivity of the three-light-absorbing material in the embodiment is 90%, and the water evaporation rate reaches 1.32kg m-2h-1The photothermal conversion rate was 88%.
Comparing the experimental data of example three and example one, it was found that the annealing temperature and hydrothermal temperature did not have a small effect on the experimental results, indicating that in practice, it was necessary to operate strictly according to the process parameters given in the present invention.
Example four
The fourth embodiment is different from the first embodiment in that the activation process parameters of the carbon fiber cloth are changed, namely: and ultrasonically cleaning the carbon fiber cloth by using absolute ethyl alcohol and deionized water for 5min, annealing the carbon fiber cloth in a muffle furnace at 450 ℃ for 2h to activate the carbon fiber cloth, carrying out no hydrothermal experiment, and carrying out performance test after the rest processes and parameters are the same as those of the first embodiment.
Tests show that the solar absorptivity of the four-light-absorption material in the embodiment is 90%, and the water evaporation rate reaches 1.14kg m-2h-1The photothermal conversion rate was 68.5%. A
Comparing the test data of the fourth example with the test data of the first example, the activated carbon fiber cloth is also subjected to photo-thermal conversion, but the photo-thermal conversion efficiency is low, which shows that the 1T/2H-MoS prepared on the activated carbon fiber cloth by the invention2The solar cell has a plurality of gaps, which are beneficial to the escape of water vapor and the transportation of water, and the densely distributed gaps simultaneously increase the refraction of light and improve the utilization rate of sunlight and the photothermal conversion efficiency.
EXAMPLE five
The fifth embodiment is different from the first embodiment in that: after the third step of example one, the sample was placed in a tube furnace and annealed at 600 ℃ in Ar atmosphere for 2h, with the remaining process and parameters the same as in example one. And then performing performance test.
Tests show that the solar absorptivity of the five-light-absorbing material in the embodiment is 92%, and the water evaporation rate reaches 1.29kg m-2h-1The photothermal conversion rate was 82.4%.
Comparing the test data of the fifth embodiment with the test data of the first embodiment, the second annealing after the preparation of the material of the invention is not beneficial to the material performance, thereby further explaining the rationality of the technical scheme of the invention.
As can be seen from the graph 2 of the contact angle of the surface of the sample in the embodiment of the invention, the composite material has good hydrophobicity, and the hydrophobic surface can well prevent the precipitated salt from being accumulated on the evaporation surface, so that the excellent evaporation efficiency is maintained and the cycling stability of the sample is improved.
An embodiment of the invention as given in figures 3a and 3b is a 500 times and 5 ten thousand times swept volume of a light absorberDrawing the appearance graph can see that MoS2The nanosheets grow uniformly on the CFC and have a plurality of voids between each other, facilitating the escape of water vapor and the transport of moisture. The densely distributed gaps simultaneously increase the refraction of light and improve the utilization rate of sunlight.
As can be seen from the X-ray diffraction pattern of the first example shown in FIG. 4, the synthesized material contains carbon cloth and 1T/2H-MoS2Ingredients, illustrating that the preparation protocol of the present invention is feasible.
As can be seen from the comparison of the mass loss of the different carbon fiber cloth samples under one illumination intensity given in FIG. 5, the 1T/2H-MoS prepared by the method of the present invention is used over time2The seawater quality of the carbon cloth sample is reduced more, which shows that the material of the invention has excellent water evaporation rate.
As can be seen from the cyclic side test chart of continuous illumination for 30h under one illumination intensity of the first embodiment shown in FIG. 6, the carbon fiber cloth composite material is stable and can be recycled.
The outdoor solar desalination experiment of the first embodiment shown in fig. 7 proves the application prospect under the true condition. Air humidity ≈ 50%, outdoor average temperature 25 ℃, time from 7 am: 00 to 17 pm: 00, although the intensity of the sunlight was 0.6kW m at the maximum in the outdoor test-2However, 1T/2H-MoS2The evaporation rate of the/A-CFC three-dimensional evaporator can still reach 1.5 kW.m-2·h-1And data obtained at 0.6 light intensity under laboratory conditions.
