  • Patent number: 8207085
    Abstract: A photocatalytic coating composition comprising photocatalytic titanium oxide, silver, copper and a quaternary ammonium hydroxide. The photocatalytic coating composition may include a photocatalytic titanium oxide sol dispersed in a binder. Furthermore, a photocatalytic member includes a substrate having a surface coated with the photocatalytic coating composition. The photocatalyst coating composition can contain highly antibacterial silver by skillfully utilizing copper and a quaternary ammonium hydroxide, and accordingly can show an antibacterial effect not only in a dark place simply due to silver, but also a higher antibacterial effect in a conventional application of employing ultraviolet sterilization by concomitantly using the photocatalyst titanium oxide sol according to the present invention and an ultraviolet sterilizer.
