The invention relates to an active carbon paper fiber with photocatalyst and a manufacturing method thereof, and more particularly to an activated carbon paper fiber with nano photocatalyst and a manufacturing method thereof . [Prior Art] A conventional photocatalyst is a photoinduced catalyst which can effectively reduce the activation energy of a chemical reaction, promote a chemical reaction or accelerate the reaction, but the catalyst itself does not participate in the reaction or destroy the bulk structure. At present, the most commonly used nano photocatalyst is titanium dioxide (Ti02) with better catalytic performance and lower cost, and light is provided by the light energy provided by ultraviolet (UV) or near-UV (near-UV) illumination. The catalytic reaction converts oxygen or water molecules around the catalyst into highly active hydroxyl radicals (〇Η·) and negative oxygen ions (〇2-), both of which have strong oxidizing power. It can effectively decompose organic pollutants and odor substances that are harmful to human health and effectively inhibit the growth of pathogens. It also has the advantages of high processing efficiency, simple operation, decontamination and antibacterial function. Only the catalytic reaction acts only on the surface of the nanophotocatalyst, so the reaction efficiency is often limited by the contact characteristics and transmission rate of the contaminant and the surface of the photocatalyst. Conventional activated carbon can be generally classified into powdered activated carbon (PAC), granular activated carbon (GAC), spherical activated carbon (SAC), and activated carbon fiber. , ACF, etc., due to the porous hole nature of activated carbon, its specific surface area is usually between 128249.doc 200932349 _~U400 mVg, that is, the adsorption capacity per unit weight of activated carbon is very large, so it is widely used in sewage treatment. Removal of contaminants such as pigments, odorous substances, insecticidal #j, antibacterial agents, and heterocyclic organic substances, and the purification of antimony pollutants. Although the adsorption effect of activated carbon is quite good, a large amount of waste activated carbon will be produced after the adsorption is saturated. The treatment cost is high, and it is easy to cause secondary pollution problems. Referring to the Republic of China, the new patent No. 257884, which uses a conventional titanium photocatalyst to directly coat or immerse a photocatalyst material on a filter network of a fluid flow system. Refer to the Republic of China new patent No. 251096, which fixes the filamentous glass fiber on a fixed net, and then encapsulates it with a + woven filter bag, soaks the liquid titanium dioxide photocatalyst solution and waits for it to dry, and then forms a photocatalyst filter. . Referring to the Republic of China invention patent No. 125472, which is cut into short fibers by using activated carbon fiber bundles, and then implanted into the hollow of the mesh carrier by vibration or spraying to develop a new type of activated carbon fiber filter. Although the pressure loss of the activated carbon fiber can be reduced, a large amount of discarded activated carbon fiber is still generated after the adsorption is saturated, and the secondary pollution problem is easily caused. Referring to the Republic of China Invention Patent Publication No. 200500523, the activated carbon fiber is immersed in a silver nitrate solution to prepare a silver-loaded activated carbon fiber, which utilizes activated carbon fiber to capture bacteria, and uses silver to inhibit bacteria, so that the activated carbon fiber achieves antibacterial effect. However, the activated carbon fiber also has a problem of adsorption saturation for other organic pollutants. In addition, refer to the Republic of China new patent No. 221965, which is a filter, ultraviolet antibacterial lamp, activated carbon and nano photocatalyst filter, windmill J28249.doc 200932349 motor assembled into an air purification device, and by ultraviolet antibacterial and Activated carbon deodorization achieves the purpose of antibacterial and air purification. The activated carbon and nano photocatalyst filter system are composed of a single activated carbon filter and a nano photocatalyst filter, and most of the materials with activated carbon photocatalyst are This type is (such as: Republic of China new patents M291359, M273694). However, the combination of multiple coffins is used for the purpose of achieving high collection efficiency, while the requirement for low wind resistance is quite difficult to achieve. If the pressure loss is too large, even if it has a good trapping effect, it cannot be widely used. In addition, the reference to the Republic of China's new patent No. M262534 is to coat the surface layer of the melamine board with a titanium dioxide photocatalyst layer, and the use of the photocatalyst layer to make use of the interior space of the melamine board without the need for other power. In the case of 'only need to use natural light or ultraviolet light to illuminate the light, it can continue to purify its space. Referring to the Republic of China, the new patent No. M320542 is composed of a light transmissive wrapping paper and a nano photocatalyst, wherein the nano photocatalyst is directly printed on the permeable transparent wrapping paper, and the light is transmitted through the permeable packaging paper. Nano photocatalysts 'decompose pesticides by photocatalysts and produce water and carbon dioxide. The above-mentioned conventional patents and methods have the effects of antibacterial, deodorizing and dust removal, but because of the combination of multiple forms, not only the problem of adsorption saturation of activated carbon, but also various paper products coated with photocatalyst are not available. Activated carbon adsorption and long-lasting functions. Therefore, it is necessary to provide an innovative and progressive nano carbon paper fiber having a nano photocatalyst and a method of manufacturing the same to solve the above problems.
