Description

Technical Field

[0001] This invention relates to a three-dimensional stacked photocatalytic device, particularly a device utilizing an adjustable irradiation angle of the photocatalytic element, suitable for various photocatalytic applications, including reactions such as water splitting to produce hydrogen and photoreduction of carbon dioxide. This three-dimensional design focuses on improving light energy utilization per unit area and enhancing photocatalytic efficiency. Prior Technology

[0002] Photocatalysis technology has shown great potential in environmental and energy applications, especially in reactions such as water splitting to produce hydrogen and photoreduction of carbon dioxide. However, existing photocatalytic devices have low light energy utilization per unit area, which prevents them from achieving optimal catalytic efficiency.

[0003] Meanwhile, developing more efficient devices to improve light energy utilization efficiency per unit area has become an important research topic. Traditional photocatalytic devices often rely on planar designs, which cannot fully utilize the limited surface area to achieve the maximum photocatalytic effect. In addition, the changing angle of light irradiation over time further reduces the overall efficiency of the photocatalytic reaction. Therefore, developing a device with a three-dimensional stacked design and adjustable light irradiation angle can effectively improve the light energy utilization rate per unit area and provide higher efficiency in the photocatalytic reaction.

[0004] Therefore, designing a highly flexible three-dimensional stacked photocatalytic device not only effectively solves the problem of unit area utilization in photocatalytic reactions but also improves the efficiency of hydrogen production from water splitting. Furthermore, it can be extended to other photocatalytic applications such as carbon dioxide photoreduction, realizing broader application value. This type of device, with its ability to adjust the irradiation angle of the photocatalytic element, can respond to changes in the irradiation angle in real time, ensuring optimal utilization of light energy and improving the overall efficiency and stability of the photocatalytic reaction.

[0005] In summary, the design of the three-dimensional stacked photocatalytic device breaks through the limitations of traditional devices in terms of utilization efficiency per unit area. It can not only effectively increase the production capacity of photocatalysts, but also improve the absorption and utilization of light through a flexible angle adjustment mechanism, providing the industry with a highly efficient and stable photocatalytic solution.

[0006] In view of the problems of the prior art, the present invention provides a three-dimensional stacked photocatalytic device. This device includes photocatalyst elements with adjustable irradiation angles.

This design is applicable to various photocatalytic reactions, including but not limited to water splitting for hydrogen production and carbon dioxide photoreduction, thereby significantly improving the conversion efficiency in renewable energy applications.

[0021] In view of the problems of the prior art, the present invention comprises a first integrated component pivotally connected to a support frame. The first integrated component, which is adjustable in angle, adjusts the irradiation angle when a light source is irradiated, so that the light source continuously and sequentially passes through the first top plate and the first photocatalyst, causing the first photocatalyst to generate a gas.

[0022] Please refer to Figure 1, which is a structural schematic diagram of the first embodiment of the present invention. As shown in the figure, this embodiment is the first embodiment, which is a three-dimensional stacked photocatalytic device, which includes a support frame 10 and a first integrated component 20, wherein the support frame 10 is used to support the first integrated component 20.

[0023] Referring again to Figures 1 and 2, Figure 2 is an exploded view of the structure of the first embodiment of the present invention. As shown in the figure, in this embodiment, a first pivot hole 12 is provided on one side of the support frame 10. The first integrated component 20 includes a first base plate 22, a first receiving groove 24, and a first top plate 26. One side of the first base plate 22 is pivotally connected to the first pivot hole 12. The first receiving groove 24 is disposed above one side of the first base plate 22. A first photocatalyst B1 is disposed inside one side of the first receiving groove 24. The first top plate 26 is disposed above one side of the first receiving groove 24. A first upper through hole 262 is provided in the corner of the first photocatalyst B1. The first upper through hole 262 communicates with the inside of the first receiving groove 24, allowing liquids and gases to flow into or out of the inside of the first receiving groove 24.

[0024] In one embodiment, the joint between the first base plate 22 and the first receiving groove 24 is sealed to prevent liquid or gas leakage.

[0025] In one embodiment, the first receiving groove 24 includes a cover 241, the cover 241 and the first receiving groove 24 sandwich the first photocatalyst B1, and the cover 241 is provided with a perforation corresponding to the first upper perforation 262 of the first top plate 26 to allow fluid or gas to pass through.

[0026] In one embodiment, the joint between the first receiving groove 24 and the first top plate 26 is sealed to prevent liquid or gas leakage.

[0027] Referring again to Figures 1 and 2, and Figures 3A to 3B and Figure 4, Figures 3A to 3B are schematic diagrams of the operation of the first embodiment of the present invention, and Figure 4 is a cross-sectional schematic diagram of the first embodiment of the present invention. As shown in the figures, this embodiment is based on the first embodiment described above. In this embodiment, the first base plate 22 of the first integrated component 20 rotates at the first pivot hole 12, and the first base plate 22 drives the entire first integrated component 20 to rotate, so as to adjust the angle of the first integrated component 20 accordingly.

[0028] Continuing from the above, in use, a liquid W is first added to the inner side of one of the first receiving tanks 24. The liquid W enters the inner side of the first receiving tank 24 through the first upper perforation 262. The liquid W soaks the first photocatalyst B1. Then, an external light L1 shines on the first top plate 26. Because the first top plate 26 is light-transmitting, the light L1 passes through the first top plate 26 and shines on the first photocatalyst B1 in the first receiving tank 24, causing the first photocatalyst B1 to decompose the liquid W and generate a gas A (only part of the figure is shown). The gas A then flows from the inner side of the first receiving tank 24 to the first upper perforation 262 and is discharged and collected.

[0029] Continuing from the above, in one embodiment, the liquid W contains water, the gas A contains hydrogen, and the first photocatalyst B1 decomposes the liquid W to produce hydrogen ions and hydroxide ions.

[0030] Continuing from the above, in one embodiment, the first photocatalyst B1 includes a first polymer material B14, which is disposed on the inner side of the first receiving groove 24.

[0032] Continuing from the above, in one embodiment, the first photocatalyst B1 further includes a first substrate B12, the first substrate B12 being disposed on the inner side of the first receiving groove 24, and the first polymer material B14 being coated on one of the first substrates B12.

[0033] Continuing from the above, in one embodiment, the wavelength of the light L1 includes 250nm to 650nm, but is not limited thereto.

[0034] Continuing from the above, in one embodiment, the first base plate 22 is provided with a reflective layer 221, which reflects the light L1 to increase the illumination of the first photocatalyst B1 and improve the photocatalytic efficiency of the first photocatalyst B1.

[0035] Please refer to Figures 5A to 5C, which are schematic diagrams of the structure and operation of the second embodiment of the present invention. As shown in the figures, this embodiment is the second embodiment, which is based on the first embodiment described above. In this embodiment, it further includes a second integrated component 30 and a second pivot hole 14 disposed above one of the first pivot holes 12 on the side of the support frame 10. The second integrated component 30 includes a connecting pipe 31, a second bottom plate 32, a second receiving groove 34, and a second top plate 36. One end of the connecting pipe 31 is connected to the first upper through hole 262 for receiving the gas A and transporting the liquid W. One side of the second bottom plate 32 is pivotally connected to the second pivot hole. 14. A lower perforation 322 is provided through the second base plate 32, which is connected to the other end of the connecting pipe 31. The second receiving groove 34 is disposed above one of the second base plates 32. A second photocatalyst B2 is disposed inside the second receiving groove 34. The second receiving groove 34 is connected to the lower perforation 322. The second top plate 36 is disposed above one of the second receiving grooves 34. A second upper perforation 362 is provided through the corner of the second photocatalyst B2 on the second top plate 36. The second upper perforation 362 is connected to the inside of the second receiving groove 34, so that liquids and gases can flow into or out of the inside of the second receiving groove 34.

[0036] In one embodiment, the joint between the second bottom plate 32 and the second receiving groove 34, and the joint between the second receiving groove 34 and the second top plate 36 are similarly sealed to prevent liquid or gas leakage.

[0037] In one embodiment, the second receiving groove 34 includes a cover 341, the cover 341 and the second receiving groove 34 sandwich the second photocatalyst B2, and the cover 341 is provided with a perforation corresponding to the second upper perforation 362 of the second top plate 36 to allow fluid or gas to pass through.

[0038] Referring again to Figures 5A to 5C and Figure 6, Figure 6 is a cross-sectional schematic diagram of the second embodiment of the present invention. As shown in the figure, this embodiment is based on the above-described second embodiment. In this embodiment, similar to the first integrated component 20, the second base plate 32 of the second integrated component 30 rotates at the second pivot hole 14, and the second base plate 32 drives the entire second integrated component 30 to rotate, so as to adjust the angle of the second integrated component 30 accordingly.

[0039] Continuing from the above, when in use, first add the liquid W to the inner side of one of the second receiving tanks 34 to soak the second photocatalyst B2. Since the second receiving tank 34 is connected to the first receiving tank 24 by the connecting pipe 31, part of the liquid W flows into the first receiving tank 24 to soak the first photocatalyst B1. Then, the external light L1 shines on the second top plate 36. Since the second top plate 36 is light-transmitting, the light L1 passes through the second top plate 36 and shines on the second photocatalyst B2 in the second receiving tank 34, causing the second photocatalyst B2 to decompose the liquid W and generate the gas A (only part is shown in the figure). The gas A then flows from the inner side of the second receiving tank 34 to the second upper perforation 362 for discharge and collection.

[0040] Continuing from the above, since the second integrated component 30 is disposed above the first integrated component 20, and the second base plate 32 of the second integrated component 30 is light-transmitting, the light L1 passing through the second integrated component 30 can be further projected onto the first integrated component 20. Its light path is the same as that of the first embodiment described above, so it will not be described again.

[0041] Continuing from the above, the gas A generated by the first integrated component 20 is transported to the inner side of the second receiving tank 34 through the connecting pipe 31, and then discharged through the second upper perforation 362 and collected.

[0042] Continuing from the above, in one embodiment, the second photocatalyst B2 includes a second polymer material B24, which is disposed on the inner side of the second receiving groove 34.

[0043] Continuing from the above, the second polymer material B24 can be polypropylene glycol (PPG), toluene-2,4-diisocyanate terminated (PTD), and 3-(4,4-bis(2-ethylhexyl)-6-methyl-4H-cyclopenta[2,1-b:3,4-b']dithiophen-2-yl)-7-methyldibenzo[b,d]thiophene-5,5-dioxide (3-(4,4-bis(2-ethylhexyl)-6-methyl-4H-cyclopenta[2,1-b:3,4-b']dithiophen-2-yl)-7-methyldibenzo[b,d]thiophene 5,5-dioxide (PCPDTDBT) and 3-methyl-7-(7-methyl-9,9-dioctyl-9H-fluoren-2-yl)-5-phenylbenzo[b]phosphindole 5-oxide (PFBPO) or any combination thereof.

[0044] Continuing from the above, in one embodiment, the second photocatalyst B2 further includes a second substrate B22, the second substrate B22 being disposed on the inner side of the second receiving groove 34, and the second polymer material B24 being coated on one of the second substrates B22.

[0045] Continuing from the above, in one embodiment, the first photocatalyst B1 and the second photocatalyst B2 are made of different materials to effectively utilize the different wavelengths of the light L1 and further improve the photocatalytic efficiency.

[0046] Please refer to Figures 7A and 7B, which are schematic diagrams of a plurality of accommodating tank structures according to one embodiment of the present invention. As shown in the figures, this embodiment is based on the first or second embodiment described above. In this embodiment, a first auxiliary accommodating tank 28 is provided above the first accommodating tank 24 of the first integrated component 20. The first auxiliary accommodating tank 28 is disposed between the first accommodating tank 24 and the first top plate 26. A first auxiliary photocatalyst B1' is provided on the inner side of one of the first auxiliary accommodating tanks 28 to further increase the amount of gas generated by the first integrated component 20.

[0047] Continuing from the above, in this embodiment, a second auxiliary receiving groove 38 is provided above the second receiving groove 34 of the second integrated component 30. The second auxiliary receiving groove 38 is disposed between the second receiving groove 34 and the second top plate 36. A second auxiliary photocatalyst B2' is provided inside one of the second auxiliary receiving grooves 38 to further increase the amount of gas generated by the second integrated component 30.

[0048] Continuing from the above, in one embodiment, multiple of the first auxiliary receiving tanks 28 may be stacked to form a photocatalytic device comprising a plurality of receiving tanks, but this is not a limitation.

Furthermore, by pivoting multiple integrated components to the support frame, the multiple integrated components capture the energy of light of different wavelengths, further increasing the efficiency of gas generation by photocatalysis and solving the problem of poor efficiency in gas generation by photocatalysis in the prior art.
