Title:
PHOTOCATALYST-COATED OBJECT AND PHOTOCATALYST COATING LIQUID THEREFOR
Document Type and Number:
WIPO Patent Application WO/2011/040405
Kind Code:
A1
Abstract:
Provided is a photocatalyst-coated object which prevents corrosion down to a substrate, particularly an organic substrate, and which also has various excellent characteristics, especially toxic gas decomposition capability and long-term retention of self-cleaning performance using the hydrophilic property of the photocatalyst. The photocatalyst-coated object comprises a substrate and a photocatalyst layer disposed on the substrate. The primary components of the photocatalyst layer are photocatalyst particles in an amount greater than 3 mass% but less than 5 mass%, and inorganic oxide particles in an amount greater than 85 mass% but less than 97 mass%, assuming that the total amount of the photocatalyst layer is 100 mass%.
