PHOTOCATALYST HYDROSOL AND WATER-BASED PHOTOCATALYST COATING AGENT

摘要

PROBLEM TO BE SOLVED: To provide a photocatalyst hydrosol excellent in dispersibility, a photocatalyst coating agent effectively maintaining photocatalytic activity and/or hydrophilicity for a long time, and a coated article. SOLUTION: The photocatalyst hydrosol is obtained by depositing 1-10 mass% of an aluminum compound on the surface of a photocatalytic particle to the photocatalytic particle, and is stable in a neutral pH range.
