Abstract
Multi-functional materials which have a photocatalytic layer with a photocatalytic function disposed on the surface of a base through an amorphous binder layer 6 interposed therebetween. Photocatalytic particles of the photocatalytic layer are joined together by a surface energy or solid-state sintering. The photocatalytic layer 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. A lower layer of the photocatalytic layer is embedded in the binder layer such that an intermediate layer is formed between the binder layer and the photocatalytic layer, the intermediate layer including components of the binder and photocatalytic layers in varying concentrations therethrough.
