Description

CROSS-REFERENCE TO RELATED APPLICATION This application claims the priority benefit of Chinese application serial No. 202110403490.X, filed on Apr. 15, 2021. The entirety of the above-mentioned patent application is hereby incorporated by reference herein and made a part of the specification. BACKGROUND OF THE INVENTION Field of the Invention The disclosure relates to an electronic device and a keyboard module thereof. Description of the Related Art Most conventional electronic devices use passive antibacterial/bacteriostatic methods, in an embodiment, surface treatment methods such as spraying, electrophoresis, and the like. An antibacterial agent or an antibacterial substance such as silver ions are added to a housing material of the electronic device. However, such passive antibacterial/bacteriostatic methods are used to only deal with bacteria or viruses falling to a specific position of the electronic device, and cannot effectively reduce bacteria or viruses dispersed in the air. BRIEF SUMMARY OF THE INVENTION The disclosure provides a keyboard module. The keyboard module includes a base plate, a plurality of key structures, a backlight module, and a photocatalyst layer. The base plate includes a plurality of openings. The plurality of key structures is disposed on the base plate and respectively corresponds to the openings. The backlight module is disposed under the base plate and includes a visible light emitting unit and an ultraviolet light emitting unit. The photocatalyst layer is coated on a lower surface of the base plate. The disclosure further provides an electronic device. The electronic device includes a first body, a second body, and a keyboard module. The second body is pivotally connected to the first body. The keyboard module is disposed on a side of the first body facing the second body. The keyboard module includes a base plate, a plurality of key structures, a backlight module, and a photocatalyst layer. The base plate includes a plurality of openings. The plurality of key structures is disposed on the base plate and respectively corresponds to the openings. The backlight module is disposed under the base plate and includes a visible light emitting unit and an ultraviolet light emitting unit. The photocatalyst layer is coated on a lower surface of the base plate. According to the keyboard module and the electronic device provided in the disclosure, hydroxyl radicals are generated by irradiating the photocatalyst layer with visible light or ultraviolet light, to reduce air bacteria or viruses in an active antibacterial/bacteriostatic manner, thereby reducing the likelihood of exposure to bacteria or viruses when a user uses the electronic device. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic cross-sectional view of a keyboard module according to an embodiment of the disclosure. FIG. 2 is a schematic top view of an embodiment of a backlight module in FIG. 1. FIG. 3 is a schematic cross-sectional view of a keyboard module according to another embodiment of the disclosure. FIG. 4 is a three-dimensional schematic diagram of an electronic device according to an embodiment of the disclosure. FIG. 5 is a schematic block diagram of the electronic device of FIG. 4. DETAILED DESCRIPTION OF THE EMBODIMENTS More detailed descriptions of the specific embodiments of the disclosure are provided below with reference to the accompanying drawings. The features and advantages of the disclosure are described more clearly according to the following description and claims. It is to be noted that all of the accompanying drawings use very simplified forms and imprecise proportions, which are only used for assisting in conveniently and clearly explaining the objective of the embodiments of the disclosure. FIG. 1 is a schematic cross-sectional view of a keyboard module according to an embodiment of the disclosure. As shown in the figure, a keyboard module 100 module includes a base plate 120, a plurality of key structures 140, a backlight module 160, and a photocatalyst layer 180. The base plate 120 includes a plurality of openings 122. The plurality of key structures 140 is disposed on the base plate 120 and respectively corresponds to the openings 122. The key structures 140 are leaf key structures, scissor-leg key structures, mechanical switch key structures, and the like. The scissor-leg key structure is used as an example in the figure. The backlight module 160 is disposed under the base plate 120. The photocatalyst layer 180 is located on a lower surface 120a of the base plate 120. A ray of light generated by the backlight module 160 is directly projected onto the photocatalyst layer 180. In one embodiment, the photocatalyst layer 180 is coated on the lower surface 120a of the base plate 120. That is to say, the photocatalyst layer 180 is formed on the lower surface 120a of the base plate 120 by coating a photocatalyst material, which is not limited thereto. In one embodiment, the photocatalyst
