Surface zeolite layer with wall coverings and surface porous object layer with wall coverings

摘要

PPROBLEM TO BE SOLVED: To increase the capability of decomposing and eliminating a toxic chemical compound by combining zeolite with photocatalyst while the capability of decomposing the toxic chemical compound is increased by titanium oxide in the presence of a weak ultraviolet ray. PSOLUTION: Powdery or granular zeolite 2 is adhered to a surface of a base material 1 so as to form a zeolite layer 3. The photocatalyst 4 is adhered, then, to the surface of the powdery/granular zeolite 2 which forms the zeolite layer 3 to form a photocatalyst layer 5. Air can freely get into contact with the photocatalyst 4 forming the photocatalyst layer 5 as well as the powdery/granular zeolite 2 forming the zeolite layer 3. The titanium oxide is a main component of the photocatalyst 4 forming the photocatalyst layer 5. PCOPYRIGHT: (C)2006,JPO&NCIPI
