摘要:
A photocatalyst-coated body comprises a substrate and a photocatalyst layer provided on the substrate, the photocatalyst layer comprising photocatalyst particles of 1 part or more by mass and less than 20 parts by mass, inorganic oxide particles of 70 parts or more by mass and less than 99 parts by mass, and the dried substance of a hydrolyzable silicone of zero parts or more by mass and less than 10 parts by mass, provided that a total amount of the photocatalyst particles, the dried substance of the inorganic oxide particles and the hydrolyzable silicone is 100 parts by mass in terms of silica. The inorganic oxide particles have a number average particle diameter ranging from 10 nm or more to less than 40 nm calculated by measuring lengths of 100 particles randomly selected from particles located within a visible field magnified 200,000 times by a scanning electron microscope.

摘要:
Disclosed are a photocatalyst-coated body that can realize a good weather resistance, a photocatalyst-coated body that, in removing NOx, particularly in removing NOx in air, can suppress the production of an intermediate product such as NO2 while increasing the NOx removed, and a photocatalytic coating liquid for use in the formation of the photocatalyst-coated body. The photocatalyst-coated body comprises a photocatalyst layer provided on a substrate. The photocatalyst layer comprises at least photocatalytic titanium oxide particles, silica particles, and a product obtained by drying water soluble zirconium compound. When the photocatalyst layer is presumed to be totally 100% by mass, the content of the photocatalytic titanium oxide particles are not less than 1% by mass and not more than 20% by mass, the content of the silica particles are not less than 51% by mass and not more than 98% by mass, and the content of the product obtained by drying water soluble zirconium compound is not less than 1% by mass and not more than 48% by mass in terms of zirconium oxide (ZrO2).
