Highly functional base material

摘要

A highly functional material characterized in that a photocatalyst comprising fine particles of rutile type titanium dioxide strongly supporting ultra-fine metal particles selected from the group consisting of Pt, Au, Pd, Rh, Pu and Ag with a particle diameter of 1 nm to 5 nm by firing treatment so as to exhibit a quantum tumbling effect of electron between the metal particles and the rutile type titanium dioxide and the photocatalyst is scattered on a surface of the base material so as to be irradiated by a light with wavelength smaller than about 407 nm.
