| description | PROBLEM TO BE SOLVED: To provide a technique of decreasing the number of times of maintenance by removing poisoned substance while using a photocatalyst filter. SOLUTION: One side 10a is provided with a porous film 2 deposited with a photocatalyst layer 1 to be irradiated with light 4. The other side 10b is provided with a removing agent 3 and comes into contact with the porous film 2. NOx 31 is subjected to a catalyst reaction in the photocatalyst layer 1 irradiated with the light 4, by which nitric acid 32 is formed. The removing agent 3 yields the nitric acid 32 passed through the porous film 2. The substance to absorb the nitric acid 32 is adopted for the removing agent 3. The nitric acid 32 may be led to the other side 10b through the porous film 2 and therefore the nitric acid 32 which is the catalyst poison to the photocatalyst layer 1 does not remain long in the photocatalyst layer 1. |
