(57) [Abstract] [PROBLEMS] An economical photocatalyst sheet capable of decomposing and removing odors and environmental pollutants in the air, or sterilizing the living environment such as antibacterial and antifungal, and preventing dirt, and a method for producing the same. I will provide a. The photocatalyst sheet of the present invention is produced by a simple method in which the surface of a sheet of an organic material such as plastic is coated with a titania sol solution, and pressure is applied while heating to carry titanium oxide powder on the surface of the sheet. Due to the redox effect of electrons and holes generated by the irradiation of light, it is easy to remove foul odors, harmful substances in the air, organic solvents dissolved in water, pesticides, and other organic compounds that contaminate the environment. It can be decomposed and removed to suppress the growth of bacteria and fungi, and can be used safely and at low cost, with energy savings, and its effects can be maintained without maintenance. |
