Abstract
Multi-functional materials are classified into those which have a photocatalytic layer with a photocatalytic function directly disposed on the surface of a base and those which have a photocatalytic layer with a photocatalytic function disposed on the surface of a base through a binder layer interposed therebetween. Photocatalytic particles of the photocatalytic layer are joined together by a surface energy or solid-state sintering. The photocatalytic layer has a structure in which fine particles fill interstices defined between photocatalytic particles. A metal such as Ag, Pt, or the like may be fixed or not fixed to surfaces of the photocatalytic particles.
