[0079] S7: Fix the metal PT (platinum) sheet described in claim 1 in a container.

[0080] Further, step S1: cleaning and surface modification of FTO conductive glass;

[0081] The FTO conductive glass was immersed in deionized water with detergent and ultrasonically cleaned for 15 minutes to remove oil and particles on the surface.

[0082] After taking it out, rinse it with deionized water for more than two times to ensure that the detergent is completely removed.

[0083] Use acetone and ethanol to sonicate for 15 min each to further remove organic residues and contaminants such as fingerprints.

[0084] Dry the FTO conductive glass with nitrogen to prevent water residue from affecting the coating quality.

[0085] The cleaned FTO conductive glass was subjected to UVO (ultraviolet ozone treatment) for 30 minutes to improve the hydrophilicity of the substrate surface and enhance the adhesion of subsequent coatings.

[0086] Further, step S2: preparing a dense titanium dioxide (c-TiO2) layer on the FTO conductive glass after UVO (ultraviolet ozone treatment);

[0087] Prepare the c-TiO2 precursor solution, accurately dissolve bis(acetylacetonato) diisopropyl titanate (75%, isopropanol) in 1 mL of n-butanol, and stir at room temperature until completely dissolved to form a 0.2 M c-TiO2 solution, which is used to form a continuous and uniform dense titanium dioxide layer.

[0088] Use a precision spin coater to evenly coat the c-TiO2 solution on the surface of the FTO conductive glass, set the rotation speed to 5000 rpm, and the spin coating time to 30 seconds to ensure the uniformity of the coating.

[0089] The spin-coated FTO conductive glass was placed on a hot plate at 125 °C for 5 min to evaporate the solvent and promote the transformation of the precursor to titanium dioxide.

[0090] The spin coating and drying steps were repeated three times to accumulate the coating thickness and ensure sufficient coverage and compactness.

[0091] The dried FTO conductive glass was placed in a preheated 500°C tube furnace for annealing for 30 minutes to eliminate stress in the coating, promote lattice arrangement, and improve the mechanical and electrical properties of the coating. After annealing, it was slowly cooled to room temperature to obtain a uniform and dense titanium dioxide layer.

[0093] The m-TiO2 solution was prepared by mixing titanium dioxide slurry with anhydrous ethanol in a mass ratio of 1:6 and stirring evenly to form a solution for preparing a mesoporous layer.

[0094] 60 μL of the evenly stirred m-TiO2 solution was spin-coated on the S2-treated FTO conductive glass at a speed of 5000 rpm for 30 seconds, and then dried on a hot plate at 125°C for 5 minutes to form a mesoporous layer.

[0095] The dried substrate was annealed in a 500° C. tube furnace for 30 minutes to promote the formation and stabilization of the mesoporous structure, and a mesoporous titanium dioxide layer was obtained after cooling.

[0101] 1 mol / L 90 Pour Sr(OH)2 (strontium-90 hydroxide) solution into the container. 90 Sr(OH)2 (strontium-90 hydroxide) not only provides radiation as a radioactive source, but also participates in electrochemical reactions as an electrolyte to realize the function of a nuclear battery.

[0102] Furthermore, the metal PT (platinum) sheet described in claim 1 is fixed in a container.

[0103] A metal PT (platinum) sheet 103a is used as the positive electrode of the nuclear battery and fixed on the other side of the container. The metal PT (platinum) sheet 103a is used as an electrode material and has good electrochemical stability and catalytic activity.

[0104] In summary, the present invention prepares a gold (Au) film on mesoporous titanium dioxide through a nuclear battery. On the one hand, due to its surface porosity, gold (Au) has the properties of nanoparticles, providing a larger contact area for electrode reactions. At the same time, the generation of surface plasma can also enhance the generation and separation of carriers and reduce the recombination of radiation-generated carriers. On the other hand, the use of a radioactive electrolyte can generate a variety of redox free radicals to provide more reaction substrates for the electrode reaction, thereby improving the battery performance. The high-energy β particles generated by the decay of 90Sr(OH)2 (strontium-90 hydroxide) first react with the solution to generate free radicals, and then the electrons excite the metal film layer to generate surface plasma, and finally interact with the semiconductor energy conversion material. Among them, the solution absorbs a part of the energy to generate a variety of free radicals, which have strong redox properties and can participate in electrode reactions. Then the electrons with reduced energy excite the gold (Au) surface plasma, forming an exponentially decaying electric field on the metal surface. Finally, the energy is deposited in TiO2 to generate carriers. Under the combined action of the Schottky formed by gold (Au) / TiO2 and the electric field formed by the metal surface plasma, the generation and separation of carriers are enhanced, the recombination of radiation-generated carriers is reduced, thereby improving efficiency and expanding the utilization of high-energy β sources. 90 Application of Sr(OH)2 (strontium-90 hydroxide) in nuclear batteries.
