Document Type and Number:
Japanese Patent JP2001025668
Kind Code:
A
Abstract:

To provide a photocatalytic corrugated filter whose corrugated shape can be maintained even being exposed to ultraviolet rays of a high intensity, whose catalytically functioning surface area is increased, and whose catalytic activity deterioration by nitrate ion and sulfate ion remaining thereon is prevented.

A photocatalytic corrugated filter comprises a sheet containing at least a photocatalyst and an inorganic adhesive as an adhesive for forming the corrugated structure. A photocatalytic corrugated filter comprises the sheet and an ultraviolet ray transmissive inorganic porous adhesive as an adhesive for forming the corrugated structure and the thickness of the adhesive in the adhesion part is proper to transmit ultraviolet rays. Further a water-resistant photocatalytic corrugated filter comprises the sheet and a mixture of alumina sol and poly(vinyl alcohol) as an adhesive for forming the corrugated structure.
