[0056] In the first aspect, Figure 1 As shown, the present application provides a method for electrolyzing seawater, the method comprising the following steps:
[0057] First, enter step S101 to construct a transition metal electrode, and modify the surface of the transition metal electrode to obtain a modified transition metal electrode;
[0058] Then, step S102 is entered to input the initial catalyst reaction conditions and the initial experimental result data into the first neural network model for iterative update to obtain improved catalyst reaction conditions, and under the improved catalyst reaction conditions, catalysts on different surfaces of the transition metal electrode are obtained;
[0059] Then, step S103 is entered to input the component content and distribution state of different surfaces of the sample electrode into the trained second neural network model, and the influence of the component content and distribution state of different surfaces of the sample electrode on the correlation of catalyst activity is analyzed to obtain a mapping relationship between the component content and distribution state and catalyst-related parameters, wherein the catalyst-related parameters include catalyst components and structures;
[0060] Then, step S104 is entered to obtain the component content and distribution state of different surfaces of the transition metal electrode, obtain the optimal relevant parameters of catalysts on different surfaces according to the mapping relationship, and obtain the optimal catalyst according to the optimal relevant parameters;
[0061] Then, the process proceeds to step S105 to add the optimal catalyst into the electrolysis device to electrolyze seawater to prepare a hypochlorous acid solution.
[0062] In step S101, the transition metal electrode refers to an electrode using transition metals (such as titanium, tungsten, molybdenum, chromium, etc.) as electrode materials. These metals are characterized by having multiple oxidation states and good electrical conductivity, making them very useful in electrochemical reactions. They are widely used in various electrochemical devices and catalysts, such as fuel cells, electrolyzers, and batteries.
[0063] In step S102, the initial catalyst reaction conditions include the reaction solvent, the reaction ligand and the reaction base parameters, which include the reaction time, temperature and concentration. Iterative updates through the first neural network model can enable the catalyst to achieve the purpose of controllable morphology. Among them, the regulation of different atmosphere pyrolysis for the adjustment of catalyst different elements can be achieved by regulating the catalyst with uniform structure and uniform particle size.
[0064] In step S103, the analysis of the influence of the component content and distribution state of different surfaces of the sample electrode on the correlation of the catalyst activity includes: using characterization technology to focus on the surface structure and element valence state differences of the transition metal electrode, and correlating them with the improved catalyst reaction conditions to obtain the influence of the component content and distribution state of different surfaces on the correlation of the catalyst activity.
[0065] Among them, characterization techniques include the use of X-ray diffractometer (XRD), scanning electron microscope, transmission electron microscope, X-ray photoelectron spectroscopy (XPS), etc., focusing on the surface structure of the electrode, the difference in element valence states, and correlating them with the synthetic preparation conditions to derive the differences in reaction conditions and material structure.
[0066] The first neural network model and the second neural network model can be a convolutional neural network (CNN) or a recurrent neural network (RNN) and their variants (such as LSTM, GRU).
[0067] In steps S104 and S105, by studying the control methods of catalyst morphology such as electrochemical control conditions and temperature control, the relationship between morphology, structure and catalytic activity and the influence of electrocatalytic selectivity are further investigated. By summarizing the synthesis conditions, the correlation with electrocatalytic activity is established. After conducting a systematic study, the influence of the electrode component content and distribution state on the catalyst performance (i.e., the mapping relationship) is summarized, so as to carry out targeted synthesis of catalysts of different components and establish the optimal catalytic composition and structure. Then, the optimal catalyst is added to the electrolysis device, and seawater is electrolyzed to prepare a hypochlorous acid solution. Compared with the prior art, it can improve the efficiency of seawater electrolysis and effectively save power consumption.
[0068] In some embodiments, the construction of a transition metal electrode and modification of the surface of the transition metal electrode include: constructing a multinary high entropy alloy transition metal electrode by electrolysis and electrodeposition combined with a high-temperature atmosphere calcination method, and modifying the surface of the transition metal electrode by phosphating and sulfiding methods.
[0069] In some embodiments, the method further includes: utilizing the cocktail effect of high entropy alloys to alloy multiple non-precious metals, which can improve the intrinsic activity and stability of the catalytic material. And increasing the specific surface area of the transition metal electrode through local low-dimensional nano-crystallization. Through local low-dimensional nano-crystallization, the specific surface area of the seawater electrolysis electrode can be increased, more active sites are exposed, the current required by the electrode is achieved, and the voltage is reduced at the same time.
[0070] In some embodiments, the method includes: constructing a pH gradient acid-base asymmetric electrolysis cell when electrolyzing seawater, specifically including: using acidic seawater as the cathode, using alkaline seawater as the anode, and providing corresponding pH gradients for cathode and anode reactions.
[0071] like Figure 2 Shown is a schematic diagram of the electrolysis of seawater according to an exemplary embodiment of the present application. Figure 2 It is an acid-base pH gradient mixed chemical coupling system based on hydrogen production by electrolysis of seawater and electrosynthesis of sodium hypochlorite. Acidic seawater is used as the cathode and alkaline seawater is used as the anode, and a suitable pH gradient is provided for the cathode and anode reactions. Since the hydrogen evolution reaction is kinetically fast in acidic media, while oxygen or chlorine evolution reactions are more easily carried out in alkaline media, acid / base mixed electrolysis can provide a more suitable pH environment for the cathode and anode. In addition, the acidic cathode avoids metal precipitation, improves electrode stability, and regulates the pH gradient effect. While effectively reducing energy consumption, a multifunctional energy-saving acid-base mixed electrolysis new device for seawater hydrogen chloride production and sodium hypochlorite co-production is realized, achieving the effect of reducing costs and increasing efficiency.
[0072] like Figure 3 As shown in FIG. 1 , it is a schematic diagram of a technical route for reducing energy consumption in electrolyzing seawater according to an exemplary embodiment of the present application. In view of the technical problems that enterprises need to solve urgently, such as high energy consumption, low yield and concentration in the electrolysis process of seawater, this project constructs an acid-base pH gradient mixed chemical coupling electrolysis system for seawater. First, a laboratory simulation module study is conducted to select electrode materials and optimize operating parameters, and then intelligent integration and amplification application tests are carried out. The technical route adopted is as follows: Figure 3 As shown, it mainly includes:
[0073] (1) Square meter level electrode preparation: Multi-component high entropy alloy transition metal electrodes are constructed by electrolysis and electrodeposition combined with high temperature atmosphere calcination. The electrode surface is modified by phosphating and sulfiding. Catalysts with different surfaces are prepared by regulating and optimizing the reaction solvent, ligand, and reaction conditions (time, temperature, concentration, etc.) to achieve the purpose of controllable morphology.
[0074] (2) Characterization of electrode physicochemical properties: Using advanced characterization techniques such as X-ray diffractometer (XRD), scanning electron microscopy, transmission electron microscopy, and X-ray photoelectron spectroscopy (XPS), we focus on the surface structure and element valence state differences of the electrodes, and correlate them with the synthesis and preparation conditions to obtain the differences between reaction conditions and material structures; at the same time, we analyze the control methods of catalyst morphology such as electrochemical control conditions and temperature control, and further investigate the relationship between morphology, structure and catalytic activity and its influence on electrocatalytic selectivity. By summarizing the synthesis conditions and establishing their correlation with electrocatalytic activity, we finally determine the optimal catalytic composition and structure.
[0075] (3) Construction and performance optimization of a 500W pH gradient seawater electrolyzer
[0076] Based on the optimization of electrodes, a new electrolytic cell was designed, focusing on the effects of different acid-base gradients on reaction voltage and reaction current, as well as the effect of pH changes on energy saving. The stability of the electrolytic cell was tested at different pH values, and the best pH gradient was obtained through system optimization to achieve the lowest working energy consumption and the highest reaction current and stability.
[0077] like Figure 4 As shown, the electrolysis device comprises a reaction barrel (1), a fourth connecting pipe (48) is fixedly connected to the right side of the top of the reaction barrel (1), a dustproof pipe is fixedly connected to the front end of the fourth connecting pipe (48), a compensation component is arranged at the top of the left side of the dustproof pipe, a third connecting pipe (46) is fixedly connected to the bottom of the left side of the dustproof pipe, a first control valve is fixedly connected to the bottom of the third connecting pipe (46), an ejector (44) is fixedly connected to the bottom of the first control valve, a delivery pump (43) is fixedly connected to the right side of the ejector (44), a second connecting pipe (42) is fixedly connected to the top of the delivery pump (43), a three-way valve (41) is fixedly connected to the rear side of the top of the second connecting pipe (42), a connecting pipe (5) is fixedly connected to the right side of the three-way valve (41), a first connecting pipe (4) is fixedly connected to the left side of the three-way valve (41), the first connecting pipe (4) is fixedly connected to the reaction barrel (1), and a refinement component is arranged on the inner side of the bottom of the reaction barrel (1).
[0078] Furthermore, the refinement component comprises a second connecting rod, a support ring is fixedly connected to the inner side of the bottom end of the reaction barrel (1), a first air inlet pipe is fixedly connected to the middle end of the inner side of the support ring, and a spiral tube is fixedly connected to the right side of the first air inlet pipe.

[0080] In some embodiments, the electrolysis device can also prepare hypochlorous acid solution by respectively introducing chlorine gas and sodium hydroxide solution into the anode and cathode. The working principle is as follows: when the electrolysis device is running, the sodium hydroxide solution is first transported into the reaction barrel through the second control valve, and the mixing blade is driven to rotate by the motor using the transmission rod, and the top solution is transported downward while stirring the solution, and then chlorine gas is transported into the spiral tube through the first air inlet pipe, and the chlorine gas is refined into bubbles with smaller diameters through the spiral tube, and the refined chlorine gas bubbles are transported to the sodium hydroxide solution for reaction, and then the second connecting pipe, the three-way valve and the delivery pump are used to transport the chlorine gas into the reaction barrel. The first connecting tube extracts the top solution and transports it back to the reaction through the ejector. During the process, the third connecting tube and the fourth connecting tube are used to extract the gas at the top of the reaction barrel through the ejector, and are remixed inside the right side of the ejector and then ejected at high speed, so that the reaction continues in the reaction barrel. At the same time, a vortex is formed in the reaction barrel by the high-speed ejected gas-liquid mixed fluid, thereby increasing the lateral stress of the bubbles, so that the bubbles can stay in the same water layer for a longer time and react for a long time. After the mixing is completed, the first connecting tube and the connecting tube are connected by rotating the three-way valve, so that cleaning water can be transported to the reaction barrel to facilitate subsequent cleaning.
