<P>PROBLEM TO BE SOLVED: To provide a noble-metal-carrying photocatalyst-particle-dispersion which exhibits an excellent photocatalytic activity and which has such a stable dispersibility that photocatalyst particles do not sediment in a dispersion medium, and to provide its photocatalyst functional product. <P>SOLUTION: The noble-metal-carrying photocatalyst-particle-dispersion possesses 0.005-1 pts.mass of a noble metal atom to 100 pts.mass of photocatalyst particles and 200 cP or lower of viscosity when the concentration of the solid content of the photocatalyst particles is 15 mass%. Niobium oxide particle is made to contain at a rate of 2-23 pts.mass to 100 pts.mass of the noble-metal-carrying photocatalyst-particle-dispersion. <P>COPYRIGHT: (C)2011,JPO&INPIT |
