Anti-Bacterial Photocatalytic Coated Apparatus

Abstract

An anti-bacterial photocatalytic apparatus includes one three dimensional object and one photocatalytic film. The three dimensional object is coated at least partially on the surface with the photocatalytic film. The thickness of the three dimension object underneath the photocatalytic film is at least 20 μm. The transparency of the photocatalytic film is at least 90%, and the thickness of the photocatalytic film is at least 300 nm. Moreover, the photocatalytic film is photocatalytic activated by ambient light with at least 95% of a spectral power distribution (SPD) in the visible light wavelength range greater than 400 nm. When such photocatalytic apparatus is disposed in an indoor environment with normal lighting, the apparatus is photocatalytic activated and can kill the bacteria and the viruses left by people through making contact with the apparatus.
