Photocatalytic material and uses thereof
First Claim
1. A photocatalytic material used to selectively inactivate a specific biologically harmful substance that may be contained in a liquid or gas to be treated, the material comprising:
- a photocatalyst; and
a holding substance having a holding part that specifically holds a specific biologically harmful substance, the holding substance being disposed in a state fixed to at least a part of a surface of the photocatalyst;
wherein the photocatalytic material is designed such that substantially all of the holding substance is disposed on the surface of the photocatalyst in a form such as to be able to specifically hold a specific biologically harmful substance in the holding part.

Abstract
The present invention relates to a photocatalytic material that can selectively inactivate a specific biologically harmful substance through photocatalysis, and uses thereof.
The photocatalytic material (21) provided by the present invention comprises a photocatalyst (23), and a holding substance (26) having a holding part (17) that specifically holds a specific biologically harmful substance, the holding substance (26) being disposed in a state fixed to at least a part of the surface of the photocatalyst (23). The photocatalytic material (21) is designed such that substantially all of the holding substance (26) is disposed on the surface of the photocatalyst in a form such as to be able to specifically hold a specific biologically harmful substance in the holding part (17).

6. A method of manufacturing a photocatalytic material used in selectively inactivating a specific biologically harmful substance that may be contained in a liquid or gas to be treated, the method comprising the steps of:
-
preparing a photocatalyst that is able to inactivate the harmful substance through photocatalysis;
disposing bridging molecules on a surface of the photocatalyst; and
bonding a holding substance having a holding part that is able to specifically hold a specific harmful substance to each of the bridging molecules disposed on the surface of the photocatalyst, this being a step of bonding the holding substance to the bridging molecules such that substantially all of the holding substance bonded to the bridging molecules comes to be in a form such as to be able to specifically hold a specific biologically harmful substance in the holding part. - View Dependent Claims (7, 8, 9, 10)
