Nano titanium dioxide has irreplaceable application advantages in air treatment, water purification, sterilization, self-cleaning materials, sunscreen skin care products, ink coatings, energy and other fields. 

1. Air pollution control: It is used for sterilization, disinfection and air pollution control because it is able to effectively remove formaldehyde, benzene series, TVOC, ammonia, nitric oxides and other pollutants. 

2. Photocatalyst purifier industry: Air purifier, industrial VOCs and exhaust treatment, water treatment and used for removal of formaldehyde, odor and industrial VOCs, as well as sterilization and disinfection. 

3. Preservative film industry: Inhibit the production of bacteria and molds and decompose ethylene and acetylene gas, so it is used for fruit and vegetable preservation and seed germination improvement. 

4. Coating and ink industry: The photocatalyst coating is used for bacteria resistance and bacteriostasis as well as removal of molds and formaldehyde. 5. Self-cleaning industry: It is used for surface self-cleaning of photovoltaic panels, buildings, glass, outer walls and car body, not affecting the beauty and transparency and reducing the cleaning frequency.
