Abstract

Multi-functional materials are classified into those which have a photocatalytic layer 2 with a photocata-lytic function directly disposed on the surface of a base 1 and those which have a photocatalytic layer 2 with a photo-catalytic function disposed on the surface of a base 1 through a binder layer 6 interposed therebetween. Photo-catalytic particles of the photocatalytic layer 2 are joined together by a surface energy or solid-state sintering. The photocatalytic layer 2 may have a structure in which fine particles fill interstices defined between photocatalytic particles or a structure in which no 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.
