[0056] In the first aspect, such asFigure 1 As shown, this application provides a seawater electrolysis method, the method comprising the following steps:

[0057] First, proceed to step S101 to construct a transition metal electrode, and then modify the surface of the transition metal electrode to obtain a modified transition metal electrode.

[0058] Then, in step S102, the initial catalyst reaction conditions and initial experimental results data are input into the first neural network model for iterative updates to obtain improved catalyst reaction conditions. Under the improved catalyst reaction conditions, catalysts on different surfaces of the transition metal electrode are prepared.

[0059] Then, in step S103, the component content and distribution state of different surfaces of the sample electrode are input into the trained second neural network model to analyze the influence of the component content and distribution state of different surfaces of the sample electrode on the catalyst activity, and obtain the mapping relationship between component content and distribution state and catalyst-related parameters, including catalyst components and structure.

[0060] Then, in step S104, the composition content and distribution state of different surfaces of the transition metal electrode are obtained, the optimal correlation parameters of the catalysts on different surfaces are obtained according to the mapping relationship, and the optimal catalyst is prepared according to the optimal correlation parameters.

[0061] Then, in step S105, the optimal catalyst is added to the electrolysis device to prepare hypochlorous acid solution by electrolyzing seawater.

[0062] In step S101, a transition metal electrode refers to an electrode that uses 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, reaction ligands, and basic reaction parameters, including reaction time, temperature, and concentration. Iterative updates using a first neural network model enable controllable catalyst morphology. Specifically, adjusting the heterogeneous elements in the catalyst through pyrolysis under different atmospheres allows the prepared catalyst to possess uniform structure and particle size.

[0064] In step S103, the analysis of the influence of the composition content and distribution state of different surfaces of the sample electrode on the catalyst activity includes: using characterization techniques to highlight 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 composition content and distribution state of different surfaces on the catalyst activity.

[0065] Characterization techniques include X-ray diffraction (XRD), scanning electron microscopy, transmission electron microscopy, and X-ray photoelectron spectroscopy (XPS), focusing on the surface structure and elemental valence state differences of the electrodes, and relating them to the synthesis and preparation conditions to determine the differences between reaction conditions and material structure.

[0066] The first and second neural network models can be convolutional neural networks (CNNs) or recurrent neural networks (RNNs) and their variants (such as LSTM and GRU).

[0067] In steps S104 and S105, the effects of electrochemical control conditions and temperature control on catalyst morphology regulation are investigated to further examine the relationship between morphology, structure, and catalytic activity, as well as its influence on electrocatalytic selectivity. The correlation between synthesis conditions and electrocatalytic activity is established by summarizing the synthesis conditions. After conducting systematic research, the influence of electrode component content and distribution on catalyst performance (i.e., the mapping relationship) is summarized, thereby enabling targeted synthesis of catalysts with different components and establishing the optimal catalytic composition and structure. Then, the optimal catalyst is added to the electrolysis device to electrolyze seawater to prepare hypochlorous acid solution. Compared with existing technologies, this method can improve seawater electrolysis efficiency and effectively save power consumption.

[0068] In some embodiments, constructing a transition metal electrode and modifying the surface of the transition metal electrode includes: constructing a multi-element high-entropy alloy transition metal electrode by a combination of electrolysis and electrodeposition and high-temperature atmosphere calcination, and modifying the surface of the transition metal electrode by phosphating and sulfidation methods.

[0069] In some embodiments, the method further includes: alloying multiple non-noble metals using the cocktail effect of high-entropy alloys, which can enhance the intrinsic activity and stability of the catalytic material; and increasing the specific surface area of ​​the transition metal electrode through localized low-dimensional nano-sizing. Localized low-dimensional nano-sizing can increase the specific surface area of ​​the seawater electrolysis electrode, expose more active sites, achieve the required current for the electrode, and simultaneously reduce the voltage.

[0070] In some embodiments, the method includes: constructing an electrolytic cell with pH gradient acid-base asymmetry during seawater electrolysis, specifically including: using acidic seawater as the cathode and alkaline seawater as the anode, and providing corresponding pH gradients for the cathode and anode reactions.

[0071] like Figure 2 The diagram shown is a schematic diagram of the principle of seawater electrolysis according to an exemplary embodiment of this application. Figure 2 This invention relates to an acid-base pH gradient mixed chemical coupling system based on seawater electrolysis for hydrogen production and sodium hypochlorite electrosynthesis. Acidic seawater serves as the cathode, and alkaline seawater as the anode, providing a suitable pH gradient for both reactions. Since the hydrogen evolution reaction is kinetically faster in acidic media, while oxygen or chlorine evolution reactions are more readily carried out in alkaline media, acid / base mixed electrolysis can provide a more suitable pH environment for the anode and cathode. Furthermore, the acidic cathode avoids metal precipitation, improves electrode stability, and regulates the pH gradient effect. This results in a multifunctional, energy-saving acid-base mixed electrolysis device that effectively reduces energy consumption while simultaneously achieving the co-production of hydrogen chlorine and sodium hypochlorite from seawater, thus achieving cost reduction and efficiency improvement.

[0072] like Figure 3 The diagram shown is a schematic representation of a technical route for reducing energy consumption in seawater electrolysis according to an exemplary embodiment of this application. Addressing the technical challenges of high energy consumption, low yield, and low concentration in seawater electrolysis, which are urgent problems for enterprises, this project constructs an acid-base pH gradient mixed chemical coupling seawater electrolysis system. First, laboratory simulations are conducted in modules to select the best electrode materials and optimize operating parameters. Then, intelligent integration and scale-up application experiments are carried out. The technical route adopted is as follows: Figure 3 As shown, it mainly includes:

[0073] (1) Preparation of square meter-level electrodes: Multi-element 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 sulfidation. By controlling and optimizing the reaction solvent, ligand, and reaction conditions (time, temperature, concentration, etc.), catalysts with different surfaces are prepared to achieve the purpose of morphology control.

[0074] (2) Characterization of Electrode Physicochemical Properties: Advanced characterization techniques such as X-ray diffraction (XRD), scanning electron microscopy, transmission electron microscopy, and X-ray photoelectron spectroscopy (XPS) were used to focus on the surface structure and elemental valence state differences of the electrodes, and to correlate them with the synthesis conditions, revealing the differences between reaction conditions and material structure. Simultaneously, the effects of electrochemical control conditions and temperature control on catalyst morphology were analyzed, further investigating the relationship between morphology, structure, and catalytic activity, as well as its influence on electrocatalytic selectivity. By summarizing the synthesis conditions and establishing their correlation with electrocatalytic activity, the optimal catalytic composition and structure were ultimately determined.

[0075] (3) Construction and performance optimization of a 500W pH gradient seawater electrolyzer

[0076] Based on the optimized electrodes, a novel electrolytic cell was designed, mainly focusing on the effects of different acid-base gradients on reaction voltage and reaction current, as well as the impact of pH changes on energy saving. The stability of the electrolytic cell was tested at different pH levels. Through system optimization, the optimal pH gradient was obtained, achieving the lowest operating energy consumption and the highest reaction current and stability.

[0077] like Figure 4 As shown, the electrolysis device includes a reaction tank (1), a fourth connecting pipe (48) is fixedly connected to the right side of the top of the reaction tank (1), a dustproof pipe is fixedly connected to the front end of the fourth connecting pipe (48), a compensation component is provided at the top left side of the dustproof pipe, a third connecting pipe (46) is fixedly connected to the bottom left side of the dustproof pipe, a first control valve is fixedly connected to the bottom end of the third connecting pipe (46), an ejector (44) is fixedly connected to the bottom end 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 tank (1), and a refining component is provided on the inner side of the bottom end of the reaction tank (1).

[0078] Furthermore, the refining component includes a second connecting rod, a support ring is fixedly connected to the inner side of the bottom of the reaction tank (1), a first air inlet pipe is fixedly connected to the middle 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 separately introducing chlorine gas and sodium hydroxide solution into the anode and cathode. The working principle is as follows: During operation, sodium hydroxide solution is first introduced into the reaction tank through a second control valve. Simultaneously, a motor drives a mixing impeller to rotate, stirring the solution and conveying the solution downwards from the top. Then, chlorine gas is introduced into the spiral tube through a first inlet pipe, and the spiral tube refines the chlorine gas into smaller bubbles. These refined chlorine bubbles are then introduced into the sodium hydroxide solution for reaction. Finally, a delivery pump utilizes a second connecting pipe, a three-way valve, and... The first connecting pipe extracts the solution at the top and transports it back into the reaction vessel via an ejector. During the process, the third and fourth connecting pipes extract the gas at the top of the reaction vessel via the ejector, remix it inside the ejector on the right side, and then spray it out at high speed, allowing the reaction to continue inside the reaction vessel. At the same time, the high-speed ejected gas-liquid mixture forms a vortex inside the reaction vessel, thereby increasing the lateral stress of the bubbles and allowing the bubbles to remain in the same water layer for a longer period of reaction. After mixing is complete, the first connecting pipe and the connecting pipe are connected by turning the three-way valve, allowing cleaning water to be supplied into the reaction vessel for subsequent cleaning.

[0083] The non-volatile memory may be a read-only memory (ROM), a programmable read-only memory (PROM), an erasable programmable read-only memory (EPROM), an electrically erasable programmable read-only memory (EEPROM), a magnetic random access memory (FRAM), a flash memory, a magnetic surface memory, an optical disc, or a compact disc read-only memory (CD ROM); the magnetic surface memory may be a disk storage device or a magnetic tape storage device.
