Document Type and Number:
WIPO Patent Application WO/2022/075416
Kind Code:
A1
Abstract:
The present invention mainly enables the achievement of a photocatalyst filter that achieves a good balance between deodorization effect and pressure loss by using a novel filter base material (a porous metal body). The present invention relates to a photocatalyst filter 6 which is obtained by affixing a photocatalyst 5 to a filter base material 4. The filter base material 4 is composed of a porous metal body 11. If t (mm) is the thickness t of the porous metal body 11 and C (ppi) is the average number of cells per 1 inch of the porous metal body 11, the product of the thickness t and the average number of cells C, namely (t × C) is from 100 to 400. It is preferable that the porous metal body 11 is formed of one or more materials that are selected from among nickel, silver, copper, aluminum, nickel chrome, nickel-tin and nickel-iron. It is preferable that the porous metal body 11 contains nickel as a constituent material.
