[0038] Example 1

[0039] Please see the appendix Figure 1 - Appendix Figure 5 This embodiment relates to a multi-physics coupling reaction device (hereinafter referred to as "reaction device"), which includes a reaction liner 1, a capacitor assembly 2, an electromagnetic assembly 3, a sound wave generating assembly 4, and a heating assembly 5. The reaction liner 1 contains a reaction chamber 11 for chemical reactions to occur; the capacitor assembly 2 includes two sets of opposing capacitor plates 21, with the reaction liner 1 sandwiched between the two capacitor plates 21, and the capacitor assembly 2 provides an electric field to the reaction chamber 11; the electromagnetic assembly 3 includes two opposing coils, with the reaction liner 1 sandwiched between the two coils, and the electromagnetic assembly 3 provides a magnetic field to the reaction chamber 11; the sound wave generating assembly 4 is located at the bottom of the reaction liner 1 and is used to emit sound waves into the reaction chamber 11; the heating assembly 5 is arranged around the bottom of the reaction liner 1 and is used to heat the reaction liner 1.

[0040] In this embodiment, the reaction liner 1 can be made of polytetrafluoroethylene (PTFE), which has excellent resistance to acids and alkalis, dissolution, corrosion, and high temperatures, and can be used as a container for most chemical reactions. The reaction liner 1 is cylindrical, and its interior is provided with a reaction chamber 11 for the chemical reaction to take place. The reaction chamber 11 is open, which facilitates the addition of other reactants or protective gases and the stirring of the solution during the reaction. Two opposing capacitor plates 21 are respectively erected on both sides of the cylindrical wall of the reaction liner 1, with a certain gap between the capacitor plates 21 and the outer wall of the reaction liner 1. The capacitor plates 21 provide an electric field in the reaction cavity 11, which is a uniform electric field. Furthermore, two opposing coils are also provided on the outer side of the cylindrical wall of the reaction liner 1 to provide a magnetic field to the reaction cavity 11, which is a uniform magnetic field. A sound wave generating component 4 is provided on the bottom outer wall of the reaction liner 1. The sound wave generating component 4 can emit sound waves into the reaction cavity 11, and the vibration frequency of the sound waves can be adjusted and controlled by the frequency of the electrical signal. The heating component 5 is ring-shaped and is also set at the bottom of the reaction liner 1 to heat the reaction cavity 11.

[0041] In this embodiment, the capacitor assembly 2, electromagnetic assembly 3, acoustic wave generating assembly 4, and heating assembly 5 can respectively provide four sets of physical fields—electric field, magnetic field, vibration field, and temperature field—to the chemical reaction inside the reaction chamber 11. Furthermore, coupling can be achieved by adjusting the distribution and magnitude of these four corresponding physical fields. Utilizing the interaction and synergistic effect between different physical fields, the chemical reaction process can be optimized and controlled, improving reaction efficiency, selectivity, and yield. This avoids the shortcomings of existing technologies that rely on coupling only two physical fields and thus require a single physical condition.

[0042] In this embodiment, the electric field strength generated by the capacitor plate 21 is determined by the applied voltage and geometric dimensions, as well as the dielectric properties between the two capacitor plates 21. Therefore, the magnitude of the electric field can be conveniently adjusted within a certain range by changing the voltage of the capacitor plate 21.

[0043] In this embodiment, the coil is a Helmholtz coil, which can generate a uniform magnetic field in a small area. The strength of the magnetic field is determined by the number of turns and the radius of the coil, as well as the magnitude of the current flowing through the coil. Because the Helmholtz coil has an open nature, it is easy to place or remove other instruments, and it can also be directly observed visually, making it a commonly used device in physics experiments.

[0044] Optionally, the reaction apparatus further includes a base 6 and a bracket 7, wherein a support portion 61 is provided on the base 6, and the reaction liner 1 is disposed on the support portion 61; two brackets 7 are disposed on the base 6, and two coils are respectively wound on the two brackets 7.

[0045] In this embodiment, the base 6 is a plate-shaped or block-shaped part, and the support part 61 is cylindrical and protrudes from the top surface of the base 6. The support part 61 can form a separate structure with the base 6 and be connected by riveting or screwing to facilitate disassembly and improve assemblability. Alternatively, it can be directly formed by one-piece molding to reduce costs. The reaction liner 1 is located above the support part 61, and the bracket 7 is an annular structure with a winding groove for fixing the coil on its outer periphery. The bracket 7 can also be connected to the base 6 by riveting or screwing to facilitate disassembly and improve assemblability. Alternatively, it can be directly formed by one-piece molding to reduce costs. In addition, the bracket 7 can protect the coil.

[0046] Optionally, the reaction apparatus further includes a support frame 8, which is detachably connected to the top of the support part 61. The reaction liner 1 is disposed on the support frame 8, which has two opposing mounting surfaces, and two capacitor plates 21 are respectively fixed on the mounting surfaces.

[0047] In this embodiment, the support frame 8 has a cuboid structure. The inner cavity of the support frame 8 is used to place the reaction liner 1. At the same time, the opposing inner walls of the support frame 8 can form mounting surfaces. The mounting surfaces can be used to screw the capacitor plate 21. Alternatively, mounting grooves can be formed on the mounting surfaces so that the capacitor plate 21 can be snapped into the mounting grooves. The top of the support frame 8 is detachably connected to the support part 61. The two can be locked with threaded fasteners. After the position of the support frame 8 is adjusted, it can be fixed with threaded fasteners.

[0048] Furthermore, the support frame 8 is rotatably connected to the support part 61.

[0049] In this embodiment, by rotating the support frame 8 to the support part 61, the capacitor plate 21 can be rotated by a certain angle when the support frame 8 is rotated, thereby changing the direction of the uniform electric field. This allows for convenient adjustment of the coupling angle between the uniform magnetic field and the uniform electric field. For example, the support frame 8 can rotate 180 degrees relative to the support part 61 in the horizontal plane.

[0050] Optionally, the sound wave generating assembly 4 includes a sound wave generator 41, which is fixed on the support frame 8. The bottom of the reaction liner 1 is provided with a sleeve 12 protruding outward. The sound wave generator 41 is detachably connected inside the sleeve 12, and the generating part of the sound wave generator 41 abuts against the inner bottom wall of the sleeve 12.

[0051] In this embodiment, the sound wave generator 41 is cylindrical. The vibration frequency of the sound wave generator 41 is controlled by the electrical signal frequency of the piezoelectric crystal. The vibration frequency of the sound wave generator 41 can be adjusted to a certain extent by changing the applied electrical signal frequency. The sound wave generator 41 is fixed on the inner bottom wall of the support frame 8. The bottom of the reaction liner 1 is provided with a sleeve 12 protruding outward. The sleeve 12 is fitted onto the sound wave generator 41, and the generating part of the sound wave generator 41 abuts against the inner bottom wall of the sleeve 12 to facilitate the transmission of vibration to the reaction solution inside the reaction liner 1.

[0052] Optionally, the heating assembly 5 includes a heating element 51 fixed on the support frame 8, and the heating element 51 is arranged around the outer periphery of the sleeve 12.

[0053] In this embodiment, the heating element 51 is an annular ceramic heating element, which is arranged around the outer periphery of the sleeve 12 to provide a power-controllable heating function. The heating element 51 is made of ceramic material, which has excellent thermal conductivity and electrical insulation, and can operate stably at high temperatures.

[0054] Furthermore, the heating element 51 and the sleeve 12 are spaced apart.

[0055] A certain gap is formed between the heating element 51 and the sleeve 12, which can provide sufficient space for the vibration of the sound wave generator 41 and the sleeve 12, and avoid the heating element 51 from affecting the vibration of the sound wave generator 41 and the sleeve 12, thereby affecting the preset vibration value.

[0056] Optionally, the support 61 is provided with an axially extending installation space, in which the power lines for the capacitor assembly 2, the acoustic wave generating assembly 4, and the heating assembly 5 are all located.

[0057] In this embodiment, the support 61 has a certain internal space, in which the electrical wiring of the capacitor assembly 2, the sound wave generating assembly 4, and the heating assembly 5 can be embedded, thereby integrating the wiring and ensuring safety and aesthetics. Furthermore, the base 6 is provided with multiple interfaces for connecting to an external power supply and controller, thereby supplying power and controlling the capacitor assembly 2, the sound wave generating assembly 4, the heating assembly 5, and the electromagnetic assembly 3.

[0058] The working principle of this reaction device will be explained below with specific examples.

[0059] Based on this reaction device, NiMo nanomaterials were prepared at room temperature using a co-precipitation method under physical field coupling conditions such as uniform electric field, uniform magnetic field, and acoustic vibration.

[0060] First, a uniform magnetic field with a magnetic field strength of 0.01T and a uniform electric field with a magnetic field strength of 0.1N / C perpendicular to its direction are selected for coupling, along with a physical field with a vibration frequency of 1000Hz. The operation steps are as follows:

[0061] First, prepare 100 mL each of NiSO4 and Na2MoO4 solutions with a concentration of 3 mmol / L. Then, adjust the current through the coil to generate a magnetic field strength of 0.01 T. Rotate the support frame 8 at an appropriate angle so that the magnetic field generated by the coil is perpendicular to the electric field generated by the capacitor plate 21. Adjust the voltage of the capacitor plate 21 to generate an electric field strength of 0.1 N / C. Adjust the electrical signal frequency of the sound wave generator 41 to a vibration frequency of 1000 Hz. Add 100 mL of the prepared NiSO4 solution to the reaction chamber 11 of the reaction liner 1, followed by slowly adding the Na2MoO4 solution while stirring. After the reaction has completed for a certain period of time, collect the precipitate to obtain NiMo nanomaterials under the coupled physical field conditions of a uniform magnetic field of 0.01 T, a uniform electric field with a perpendicular electric field strength of 0.1 N / C, and a vibration frequency of 1000 Hz.

[0062] Example 2

[0063] This embodiment is basically the same as the first embodiment. The sound wave generating component 4 includes a sound wave generator 41, which is fixed on the support frame 8. The difference is that the bottom of the reaction liner 1 is recessed inward and has a mounting groove. The sound wave generator 41 is detachably connected in the mounting groove, and the generating part of the sound wave generator 41 abuts against the inner bottom wall of the mounting groove.

[0064] A recessed mounting groove is used at the bottom of the reaction liner 1, and the sound wave generator 41 is embedded in the mounting groove to realize the connection between the reaction liner 1 and the support frame 8. Specifically, it can be connected by snap-fit ​​or screw connection. By providing a recessed mounting groove at the bottom of the reaction liner 1, the material cost of the reaction liner 1 can be saved and the economy can be improved.
