Abstract
Description
Technical Field
[0001] This utility model relates to the field of in-situ characterization technology, specifically to an electrochemical in-situ ultraviolet testing cell. Background Technology
[0002] As materials science research deepens, researchers urgently need to conduct more in-depth studies on the mechanisms of action, structural changes, and factors affecting the performance of materials. However, traditional non-in-situ research methods can no longer meet current needs. Take catalysis as an example: researchers often use various characterization techniques and instruments to understand the structure of catalysts, thereby better constructing the structure-activity relationship between catalyst structure and performance. However, traditional non-in-situ characterization methods can only test the state of the catalyst before and after the reaction, and cannot achieve dynamic testing during the process. In-situ characterization techniques, developed over the past thirty years, can use different instruments to perform "online" analysis of specific reaction processes. As a technique that continuously and synchronously analyzes substances through specific devices, ultimately obtaining a series of results with time or other relevant conditions as parameters, it achieves the analysis of changes in the reaction process, possessing dynamic, real-time, and intuitive characteristics. Again, taking catalyst research as an example, it can conduct transient reaction studies of catalytic reactions, and the results have an irreplaceable promoting effect on catalyst selection and design. Furthermore, in-situ characterization techniques allow for real-time observation of chemical reaction processes, material structures, and morphologies, providing information such as reaction intermediates. This aids researchers in analyzing reaction mechanisms, thereby promoting further development in chemistry and materials science. A review of recent top-tier journals in materials, catalysis, and energy storage reveals that most utilize in-situ characterization techniques for in-depth research on their subjects.

[0005] This utility model provides an electrochemical in-situ ultraviolet testing cell, including a cathode chamber and an anode chamber. The anode chamber is disposed on one side of the cathode chamber.

[0015] 3.

Detailed Implementation
[0024] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.
[0025] Please see Figures 1-4An electrochemical in-situ ultraviolet testing cell includes a cathode chamber 1 and an anode chamber 2. The anode chamber 2 is disposed on one side of the cathode chamber 1. A cathode sealing cover 3 is disposed at the top of the cathode chamber 1, and a platinum wire electrode inlet 6 is installed at the midpoint of the surface of the cathode sealing cover 3. An anode sealing cover 4 is fixedly installed on the top of the anode chamber 2. The anode sealing cover 4 is located on one side of the cathode sealing cover 3, and a liquid inlet 5 is installed obliquely on one side of the anode chamber 2. An air inlet 7, an air outlet 8, and a reference electrode inlet 9 are arranged obliquely on the top of the anode sealing cover 4. The air outlet 8 is located between the air inlet 7 and the reference electrode inlet 9.
[0026] In this embodiment, the cathode sealing cover 3 and the anode sealing cover 4 are fixedly connected to the cathode chamber 1 and the anode chamber 2 through the positioning pin hole, and the circular groove in the middle of the sample tank 11 penetrates the interior of the anode chamber 2. The surface of the liquid inlet 5 is equipped with a sealing cover, and the interiors of the cathode chamber 1 and the anode chamber 2 are both provided with grooves.
[0027] The electrochemical in-situ ultraviolet testing cell of this invention has a cathode chamber 1, which is the region where electrons flow in, controlling the cathode potential to create suitable conditions for the reduction reaction. The anode chamber 2 is the region where electrons flow out, where reactants lose electrons and undergo oxidation. At the same time, electrons released from the anode flow through the external circuit to the cathode to maintain charge balance. The coordinated design of the anode chamber 2 and the cathode chamber 1, separated by an ion exchange membrane, can effectively prevent product mixing. The setting of the gas inlet 7 and the gas outlet 8 can regulate the reaction atmosphere and discharge product gases. The distance between one end of the reference electrode inlet 9 and the electrode can be controlled to 1 cm to ensure the electric field distribution of the reference electrode and eliminate the shielding effect.
[0028] For details, please refer to the following: Figure 2 As shown, a sample groove 11 of equal width is installed on the front of the anode chamber 2, and a sealing gasket 10 is provided between the sample groove 11 and the anode chamber 2. The surface of the sealing gasket 10 abuts against the surface of the sample groove 11, and the back of the sealing gasket 10 abuts against the surface of the anode chamber 2.
[0029] For details, please refer to the following: Figure 3 As shown, a circular groove is provided in the middle of the front of the sample groove 11, and an FTO sample 13 is installed behind the groove inside the sample groove 11. A sealing gasket 12 is installed on one side edge of the sample groove 11, and the FTO sample 13 abuts against the side of the sealing gasket 12. A sample fixing groove 14 is provided on the outside of the FTO sample 13, and the back of the sample fixing groove 14 abuts against the surface of the FTO sample 13. The sample fixing groove 14 has slots on both sides.
[0030] For details, please refer to the following: Figure 3As shown, a quartz light window 15 is installed behind the FTO sample 13, and the quartz light window 15 is located on the back of the anode chamber 2. The outer surface of the anode chamber 2 abuts against the bottom of the light window fixing groove 16. The quartz light window 15 is located inside the light window fixing groove 16. A base 17 is installed at the bottom of the cathode chamber 1 and the anode chamber 2, and a groove is provided on one side of the base 17.
[0031] This invention relates to an electrochemical in-situ ultraviolet testing cell that utilizes copper tape as the working electrode. The adhesive side of the copper tape is in contact with the front side of the sealing gasket 10, which isolates the adhesive side from the material. This isolates the non-adhesive side of the copper tape from the side of the FTO sample 13. This isolation maintains a stable reaction atmosphere. Simultaneously, the sealing gasket 10 fixes the position and buffers the front-end pressure, preventing deformation from the four sides of the circular groove and ensuring smooth introduction of the copper tape. Furthermore, the sealing gasket 10 fills the gap between the anode chamber 2 and the sample tank 11 to prevent liquid leakage. The FTO sample 13 serves as a conductive substrate for dispersing the organic solution. The isolation of the solution material inside the FTO sample 13 by the quartz window 15 further enhances the conductivity and stability of the FTO material during testing.
[0032] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
