PHOTOCATALYTIC COATING COMPOSITION AND PHOTOCATALYST-BEARING STRUCTURE

摘要

A photocatalyst-bearing structure usable particularly under a high-temperature and high-humidity environment and an outdoor environment where alkali resistance is required; and a photocatalytic coating composition for the preparation of the structure. The composition is characterized by comprising a photocatalyst and a zirconium compound and/or a tin compound for imparting alkali resistance. The structure comprises an adhesive layer provided between a photocatalyst layer and a carrier, characterized in that the photocatalyst layer comprises a photocatalyst and a zirconium compound and/or a tin compound for imparting alkali resistance.
