<p>Disclosed are a photocatalyst-coated body that can realize a good weather resistancce, a photocatalyst-coated body that, in removing NOx, particularly in removing NOx in air, can suppress the production of an intermediate product such as NO 2 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 (ZrO 2 ).</p> |
