Abstract
The present invention relates to photocatalyst-carrying structures which can be used particularly in an environment of high temperature and humidity or outdoor environment requiring alkali resistance and also to composites of photocatalyst coating materials to produce the said structures. The composites of photocatalyst coating materials are characterized in containing a photocatalyst and a zirconium compound and/or tin compound in order to endow alkali resistance. The photocatalyst-carrying structure has an adhesive layer between a photocatalyst layer and a carrier. The photocatalyst layer contains a photocatalyst, and a zirconium compound and/or tin compound to endow alkali resistance.
