MULTI-FUNCTIONAL MATERIAL HAVING PHOTO-CATALYTIC FUNCTION AND PRODUCTION METHOD THEREFOR

摘要

The multi-functional material according to the present invention is divided into a type in which a photo-catalytic layer having a photo-catalytic function is directly disposed on the surface of a substrate (1) and another in which the photo-catalytic layer (2) is indirectly disposed on the surface of the substrate (1) through a binder layer (6). The mode of binding of photo-catalytic particles constituting the photo-catalytic layer (2) includes binding by surface energy and binding by solid phase sintering. The structure of the photo-catalytic layer (2) includes the structure in which fine particles are packed into gaps between the photo-catalytic particles and another in which they are not. Further, there is a structure in which metals such as Ag and Pt are fixed to the surfaces of the photo-catalytic particles and another in which they are not.
