1. Nanometer scale. The supported TiO2 particles on the surface of the photocatalytic filter cotton net are nano-scale, the particle size is 5-10 nm, and the crystal phase is anatase phase, which has good photocatalytic activity, self-cleaning ability and ultraviolet absorption ability.

2. The load is firm. The photocatalyst filter cotton net obtained by the loading method was soaked, immersed in water for ultrasonic treatment, scraping, washing and other treatments, and no nano TiO2 particles were found to fall off.

3. Filter cotton base. This product selects filter cotton material as the load base, with the advantages of large air contact area, large photocatalytic load, small gas flow resistance, etc., to improve its application effect in air purification and other fields.

4. Excellent performance. Rhodamine B dye was drip-coated on the obtained photocatalyst filter cotton net, and the color of Rhodamine B could be removed after drying under sunlight for half an hour, which proved that the photocatalytic self-cleaning effect was good. The photocatalytic filter cotton net product has high photocatalytic efficiency, good disinfection and bactericidal effect, and has remarkable application effect in air purification, odor elimination, sterilization and disinfection, water purification, decoration, aldehyde removal, deodorization and other fields. Compared with similar products sold in the market, this product has obvious effect in removing formaldehyde, ammonia, benzene, TVOC, cat poop smell, tobacco smell, butyric acid smell and other items, and has better performance.

5. The shape of the photocatalytic filter cotton net product is adjustable, the porosity size is adjustable, and different shapes of purification structural units can be prepared, which is suitable for different industries or the special needs of different manufacturers, and can be customized according to requirements.

Photocatalyst filter can be used in air purifiers, air conditioners, automotive purification systems, factory workshop air purification, industrial waste gas treatment and other fields. It is an ideal new air purification filtration product for air purification equipment. Photocatalyst filter is suitable for air purification treatment in various large places, including buildings, laboratories, factories and other large waste gas treatment; Photocatalyst filters are used in hospitals, operating rooms, IVF incubators, nurseries, kindergartens, families, conferences and other places. Room and other air purification equipment
