A photocatalyst-coated object which is excellent in weatherability, the ability to decompose a harmful gas, and other desired properties (ultraviolet absorption, transparency, film strength, etc.) while preventing the base from eroding; and a photocatalytic coating fluid. The photocatalyst-coated object comprises a base and a photocatalytic layer formed on the base. The photocatalytic layer comprises 1-20 parts by mass, excluding 20 parts by mass, of photocatalyst particles, 70-99 parts by mass, excluding 99 parts by mass, of inorganic oxide particles, 0-10 parts by mass, excluding 10 parts by mass, of a hydrolyzable silicone, and 0-10 parts by mass, excluding 10 parts by mass, of a surfactant, the sum of the photocatalyst particles, inorganic oxide particles, and hydrolyzable silicone being 100 parts by mass.
L'invention concerne un objet revêtu d'un photocatalyseur qui présente une excellente tenue aux intempéries, la capacité de décomposer un gaz nuisible, et d'autres propriétés souhaitées (absorption des ultraviolets, transparence, solidité du film, etc.) tout en empêchant la base de s'éroder ; et concerne un fluide de revêtement photocatalytique. L'objet revêtu d'un photocatalyseur comprend une base et une couche photocatalytique formée sur la base. La couche photocatalytique comprend 1-20 parties en masse, 20 parties en masse non incluses, de particules photocatalytiques, 70-99 parties en masse, 99 parties en masse non incluses, de particules d'oxyde inorganique, 0-10 parties en masse, 10 parties en masse non incluses, de silicone hydrolysable, et 0-10 parties en masse, 10 parties en masse non incluses, d'un agent de surface, la somme des particules photocatalytiques, des particules d'oxyde inorganique, et de la silicone hydrolysable représentant 100 parties en masse.
