[0038] It should be understood that the specific embodiments described herein are merely for explaining the present invention and are not intended to limit the present invention.

[0039] An embodiment of the present application provides a water purification method based on photothermal catalysis. The execution subject of the water purification method based on photothermal catalysis includes, but is not limited to, at least one of electronic devices such as a server, a terminal, etc. that can be configured to execute the method provided by the embodiment of the present application. In other words, the water purification method based on photothermal catalysis can be executed by software or hardware installed on a terminal device or a server device. The server includes, but is not limited to: a single server, a server cluster, a cloud server, or a cloud server cluster, etc.

[0040] Embodiment 1:

[0041] Referring to Figure 1 As shown, it is a schematic flowchart of a water purification method based on photothermal catalysis provided by an embodiment of the present invention. In this embodiment, the water purification method based on photothermal catalysis includes:

[0042] S1. Obtain bamboo fiber materials of a preset scale size, and perform an ultrasonic cleaning operation on the bamboo fiber materials using a pre-constructed first cleaning solution to obtain clean bamboo fibers.

[0043] It should be known that the bamboo fiber materials refer to fiber materials extracted from bamboo. Bamboo fibers have many excellent properties, including light weight, high strength, wear resistance, corrosion resistance, etc. In the embodiment of the present invention, the bamboo fiber materials provide better support for the subsequent modification of carbon nanotubes and nitrogen-doped carbon nanotubes. In addition, due to the high toughness of bamboo fibers, the mechanical properties during the subsequent product application, such as tensile strength and wear resistance, can also be improved.

[0044] In the embodiment of the present invention, the pre-constructed photocatalytic material belongs to a nano-level material. During the preparation process, the bamboo fibers need to be cut and cleaned first. To adapt to the application scenario of this solution, a water purification device of an appropriate size is constructed, and bamboo fibers in the shape of a 2 cm × 25 cm rectangular strip are used for preparation.

[0045] Then, during the cleaning process, the present invention adopts the method of ultrasonic cleaning, which can not only remove the stains on the surface of the bamboo fibers, but also form tiny grooves and cracks on the surface of the bamboo fibers, increasing the surface area, making it easier for nitrogen-doped carbon nanotubes or carbon nanotubes to adsorb and bind to the surface of the bamboo fibers, and improving the subsequent modification effect.

[0046] Further, the first cleaning solution used in the present invention is deionized water and ethanol solution. The deionized water is purified water that has undergone deionization treatment and contains no solutes and ions, which can effectively remove dust, impurities, and pollutants on the surface of bamboo fibers and purify the surface; while ethanol has good solubility and can effectively dissolve organic substances on the surface, such as resin, grease, etc.

[0047] The present invention realizes cleaning the bamboo fiber material into clean bamboo fibers through the above ultrasonic cleaning and cleaning solution.

[0048] S2. Use the pre-constructed carbon nanotube solution and an oven at a preset first temperature to perform an impregnation and drying operation on the clean bamboo fibers for a preset first number of times to obtain carbon nanotube-modified bamboo fiber fabric, and use the pre-constructed nitrogen-doped carbon nanotube solution and an oven at a preset second temperature to perform an impregnation and drying operation on the clean bamboo fibers for a preset second number of times to obtain nitrogen-doped carbon nanotube-modified bamboo fiber fabric.

[0049] In the embodiments of the present invention, when preparing carbon nanotube-modified bamboo fiber fabric and nitrogen-doped carbon nanotube-modified bamboo fiber fabric, 10 g / L carbon nanotube solution and 10 g / L nitrogen-doped carbon nanotube solution are used respectively. Each soaking lasts for 1 hour during the soaking process, and then drying is carried out in an oven at 65°C. Such soaking-drying steps are repeated 3 times to obtain carbon nanotube-modified bamboo fiber fabric (abbreviated as CBF) and nitrogen-doped carbon nanotube-modified bamboo fiber fabric (abbreviated as NCBF). Among them, the carbon nanotubes have excellent mechanical properties and electrical conductivity, which can enhance the strength and electrical conductivity of bamboo fiber fabric. After being modified with carbon nanotubes, the hydrophobicity, wear resistance, and antibacterial properties of bamboo fiber fabric can be improved, and its surface properties can be improved; while during the modification process of nitrogen-doped carbon nanotubes, more active sites can be provided, the antioxidant properties of bamboo fiber fabric can be improved, and the service life of the material can be extended.

[0050] The present invention can provide support for the subsequent attachment of the photothermal catalyst by constructing the above two nanotube-modified bamboo fiber fabrics.

[0051] S3. Use the pre-constructed cobalt nitrate hexahydrate and copper nitrate trihydrate to prepare a metal ion solution.

[0052] Specifically, in the embodiments of the present invention, the preparation of the metal ion solution using the pre-constructed cobalt nitrate hexahydrate and copper nitrate trihydrate includes:

[0053] Dissolve 4 mmol of cobalt nitrate hexahydrate Co(NO3)2·6H2O and 2 mmol of copper nitrate trihydrate Cu(NO3)2·3H2O in 60 mL of distilled water to obtain a mixed solution, and stir the mixed solution for 10 minutes to obtain a metal ion solution.

[0054] In the embodiment of the present invention, when cobalt nitrate hexahydrate and copper nitrate trihydrate are mixed, a pink solution will be formed.

[0055] In the embodiment of the present invention, through the reduction reaction of metal ions in the metal ion solution and the coordination or reaction with other functional compounds, composite nanoparticles or nanostructures composed of different metal elements can be prepared. Therefore, the metal ion solution in the present invention can be used as one of the basic materials for preparing multi-component composite nanomaterials, providing key raw materials and starting substances for constructing efficient photothermal catalysts.

[0056] S4. According to a preset solution preparation strategy, use pre-constructed thiourea and ethylenediamine activators to dissolve the metal ion solution to obtain a brown solution. The solution preparation strategy includes the addition dosage and addition order of the thiourea and ethylenediamine activators, and also includes the stirring degree after the addition of each of the thiourea and ethylenediamine activators.

[0057] Among them, the preset solution preparation strategy is a preferred solution preparation process obtained from experimental data, including dosage, order, and stirring degree, etc.

[0058] Specifically, in the embodiment of the present invention, the step of dissolving the metal ion solution with pre-constructed thiourea and ethylenediamine activators according to a preset solution preparation strategy to obtain a brown solution includes:

[0059] According to the preset solution preparation strategy, dissolve 4 mmol of thiourea into the metal ion solution and stir rapidly for 15 minutes to obtain a primary stirred solution;

[0060] Add 2 mL of ethylenediamine activator to the primary stirred solution and stir until the primary stirred solution turns brown to obtain a brown solution.

[0061] Specifically, in the embodiments of the present invention, 4 mmol of thiourea is stirred into a metal ion solution and rapidly stirred for 15 minutes to cause a reaction between the thiourea and the metal ions, forming a metal sulfide complex, which may lead to the formation of metal sulfide precipitates; then 2 mL of ethylenediamine activator is added to the primary stirred solution. Ethylenediamine may act as a reducing agent and continue to promote the formation process of metal sulfides. The ethylenediamine activator can regulate the conditions during the reaction and accelerate the precipitation of metal sulfides and / or the formation of nanoparticles. Finally, the solution is stirred until it turns brown. The formation of the brown solution indicates that metal sulfide nanoparticles have been formed. The brown solution may indicate that the size and morphology of the metal sulfide particles have specific absorption properties, which are potentially significant for photothermal catalytic applications.

[0062] Therefore, through the above process, the present invention forms a brown solution containing metal sulfide nanoparticles.

[0063] S5. Using a pre-constructed autoclave with a polytetrafluoroethylene liner, perform a high-temperature reaction on the brown solution, carbon nanotube-modified bamboo fiber fabric, and nitrogen-doped carbon nanotube-modified bamboo fiber fabric for a preset duration to obtain a high-temperature product, and cool the high-temperature product to obtain a cooled substance.

[0064] Specifically, in the embodiments of the present invention, the autoclave with a polytetrafluoroethylene liner is 100 mL, and the above brown solution is about 60 mL. The present invention introduces the brown solution together with the carbon nanotube-modified bamboo fiber fabric and nitrogen-doped carbon nanotube-modified bamboo fiber fabric produced in S2 into the autoclave to start the high-temperature reaction.

[0065] During the high-temperature reaction process of the present invention, it is maintained at 200 °C for 20 hours, and then taken out after cooling to room temperature.

[0066] S6. Using a pre-constructed second cleaning solution and an oven at a preset third temperature, perform a cleaning and drying operation on the cooled substance to obtain the first composite photothermal catalyst bamboo fiber fabric corresponding to the carbon nanotube-modified bamboo fiber fabric and the second composite photothermal catalyst bamboo fiber fabric corresponding to the nitrogen-doped carbon nanotube-modified bamboo fiber fabric.

[0067] Furthermore, in the embodiments of the present invention, the substance generated in step S5 is cleaned with distilled water and ethanol solution and dried in an oven at 50 °C for 6 hours to obtain a black substance, that is, the composite photothermal catalysts CBF-CuCo2S4 (CCBF) and NCBF-CuCo2S4 (CNCBF) loaded on the bamboo fiber fabric.

[0068] S7. Use the first composite photothermal catalyst bamboo fiber fabric and the second composite photothermal catalyst bamboo fiber fabric to form a water purification device to purify the water source.

[0069] In the embodiments of the present invention, with reference to Figure 2 As shown, the black substance can be placed in a light-transmitting container to form a water purification device, and the first composite photothermal catalyst bamboo fiber fabric and the second composite photothermal catalyst bamboo fiber fabric are stored in the water purification device in a folded 3D peak-shaped structure; there is at least one 3D peak-shaped structure in the water purification device.

[0070] Among them, Figure 2 Due to the limitation of image expression ability, only a single-peak-shaped structure and a double-peak-shaped structure are shown. In specific application scenarios, multiple layers, such as three or four 3D peak-shaped water purification device structures, can be adopted according to the water purification level and the size of the water purifier.

[0071] In the embodiments of the present invention, the 3D peak-shaped design provides a larger surface area and side area to promote the absorption of sunlight and the evaporation of water, obtains additional energy from the surrounding environment during the solar steam generation process, and improves the photocatalytic degradation efficiency by significantly increasing the contact area with organic pollutants and the fully exposed active sites.

[0072] Furthermore, with reference to Figure 3 As shown, in the embodiments of the present invention, the use of the first composite photothermal catalyst bamboo fiber fabric and the second composite photothermal catalyst bamboo fiber fabric to form a water purification device to purify the water source includes:

[0073] S71. Connect the water purification device to the water inlet, and let the water source to be purified flow through the first composite photothermal catalyst bamboo fiber fabric and the second composite photothermal catalyst bamboo fiber fabric;

[0074] S72. Catalyze the first composite photothermal catalyst bamboo fiber fabric and the second composite photothermal catalyst bamboo fiber fabric with solar energy to obtain active oxidation substances;

[0075] S73. Use the active oxidation substances to perform a photothermal catalytic pollutant degradation operation on the water source to be purified to obtain a purified water source.

[0076] In the embodiments of the present invention, the photothermal catalytic mechanism of the multi-component composite nanomaterial is used in the scenario of seawater pollutant degradation. By using the photothermal synergistic coupling and the thermal-assisted photocatalytic effect, combined with the high-efficiency light absorption performance and the photothermal conversion characteristics of the carbon material full-spectrum photothermal catalytic material, the co-oxidant is synergistically activated to generate high-concentration and various types of active oxidation substances, and the pollutants are photothermally catalytically degraded using sunlight as the energy source.

[0077] Compared with the problems described in the background art, the present invention first constructs clean bamboo fibers, and then constructs carbon nanotube-modified bamboo fiber fabrics and nitrogen-doped carbon nanotube-modified bamboo fiber fabrics with carbon nanotube solutions and nitrogen-doped carbon nanotube solutions respectively. The two fabrics have high-efficiency light absorption performance and photothermal conversion characteristics, which can provide a large amount of energy for the subsequent photocatalytic process. Moreover, the easily bendable layered structure can provide an attachment range on both the front and back sides for the subsequent photocatalyst. And the two bamboo fiber fabrics can be bent into a 3D peak structure, which can further accommodate a larger area of bamboo fiber fabrics in a fixed space. Further, the present invention constructs a new multi-component composite nanomaterial with substances such as cobalt nitrate hexahydrate, copper nitrate trihydrate, thiourea, and ethylenediamine active agent, realizes the use of photothermal synergistic coupling and thermal-assisted photocatalytic effects, combines the high-efficiency light absorption performance and photothermal conversion characteristics of carbon-based full-spectrum photocatalytic materials, synergistically activates the co-oxidant, and generates high-concentration and various types of reactive oxygen species, and uses sunlight as an energy source to achieve photocatalytic degradation of pollutants. Therefore, the main purpose of the water purification method based on photocatalysis proposed by the present invention is to provide a multi-component composite nanomaterial for efficient degradation of pollutants and construct a 3D structure degradation contact surface to further improve the single-time pollutant degradation level.
