Abstract
An environment-purifying material is obtained by immersing a carrier with a titanium oxide film coated on its surface or a substrate comprising titanium oxide particles, in a pseudo-body fluid containing an excessive amount of calcium phosphate, and then coating the surface of the substrate with a porous calcium phosphate film that easily adsorbs toxic substances and that is inactive as a photocatalyst.
