Abstract

Official abstract text for this publication.

There is provided a photocatalyst sheet comprising a base material and a photocatalyst layer containing at least a photocatalyst, wherein the photocatalyst layer is firmly adhered to the base material. In an embodiment, there is provided a photocatalyst sheet comprising a base material; and a photocatalyst layer that contains at least a photocatalyst, and is formed on at least one surface of the base material through an aerosol deposition method. This photocatalyst sheet has an excellent photocatalytic activity and an excellent adhesion.

First claim

Opening claim text (preview).

The invention claimed is: 1. A photocatalyst sheet comprising: a base material; and a photocatalyst layer that contains at least a photocatalyst, wherein the photocatalyst is formed on at least one surface of the base material by aerosol deposition performed at a pressure between 10 and 1,000 Pa, wherein the photocatalyst layer contains a co-catalyst, wherein the photocatalyst contains titanium(IV) oxide or tin(IV) oxide, and the co-catalyst contains copper(I) oxide or copper(II) oxide, and wherein the co-catalyst is supported on the photocatalyst, and wherein the mass ratio of photocatalyst to co-catalyst is about 1:1 to about 2:1. 2. The photocatalyst sheet according to claim 1 , wherein the base material is a porous film. 3. The photocatalyst sheet according to claim 1 , wherein the base material is formed of a resin. 4. The photocatalyst sheet according to claim 3 , wherein the resin includes a thermosetting resin, a thermoplastic resin, an ultraviolet curable resin, or an electron beam curable resin. 5. The photocatalyst sheet according to claim 1 , wherein the photocatalyst shows a visible-light responsiveness. 6. A method for producing the photocatalyst sheet of claim 1 , the method comprising forming a photocatalyst layer containing at least a photocatalyst on at least one surface of a base material by aerosol deposition, wherein the aerosol comprises the photocatalyst, and wherein the aerosol deposition is performed at a pressure between 10 and 1,000 Pa. 7. A photocatalyst sheet comprising: a base material; and a photocatalyst layer that contains at least a photocatalyst, wherein the photocatalyst is formed on at least one surface of the base material by aerosol deposition performed at a pressure between 10 and 1,000 Pa, wherein the photocatalyst layer contains a co-catalyst, wherein the photocatalyst contains tungsten(VI) oxide, and the co-catalyst contains cerium(IV) oxide, and wherein the mass ratio of photocatalyst to co-catalyst is about 1:1 to about 2:1. 8. The photocatalyst sheet according to claim 7 , wherein the base material is a porous film. 9. The photocatalyst sheet according to claim 7 , wherein the base material is formed of a resin. 10. The photocatalyst sheet according to claim 9 , wherein the resin includes a thermosetting resin, a thermoplastic resin, an ultraviolet curable resin, or an electron beam curable resin. 11. The photocatalyst sheet according to claim 7 , wherein the photocatalyst shows a visible-light responsiveness. 12. A method for producing the photocatalyst sheet of claim 7 , the method comprising forming a photocatalyst layer containing at least a photocatalyst on at least one surface of a base material by aerosol deposition, wherein the aerosol comprises the photocatalyst, and wherein the aerosol deposition is performed at a pressure between 10 and 1,000 Pa.
