| 摘要 |
The purpose of the present invention is to provide a photocatalyst-supporting structure which exhibits sufficient photocatalyst activity without causing degradation in a base material. The used photocatalyst-containing coating liquid contains fine particles of a photocatalyst material, at least one silane coupling agent selected from an epoxy silane coupling agent and an acrylic silane coupling agent, and/or a hydrolysis-condensation product of the silane coupling agent, a metal coupling agent which does not contain silicon as a metal element, and a solvent, wherein with respect to 100 parts by mass of the fine particles of the photocatalyst material, the total of the silane coupling agent and the hydrolysis-condensation product of the silane coupling agent is contained at a ratio of at least 300 parts by mass. |
