Document Type and Number:
WIPO Patent Application WO/2014/141812
Kind Code:
A1
Abstract:
Provided are a photocatalytic titanium oxide capable of demonstrating antibacterial and antiviral effect when used in various applications, as well as an antibacterial, antiviral photocatalytic titanium oxide slurry in which the photocatalytic titanium oxide has been stably dispersed in a neutral area, and a method for manufacturing same. An antibacterial, antiviral photocatalytic titanium oxide, wherein 0.1 to 50 mass by weight in terms of the copper standard of at least one species selected from copper (II) phosphate and copper (II) pyrophosphate with respect to 100 mass by weight of titanium oxide particles is carried on at least the surface of the titanium oxide particles, and the 50% cumulative particle diameter (D50) (light scattering intensity standard) is 5 to 200 nm.
