Abstract
A photocatalystic decomposing apparatus comprises absorbent including honeycomb form active carbon and titanium oxide acting as photocatalyst applied to a surface of the active carbon, and a light source for generating ultraviolet rays exciting the photocatalyst. Stink ingredient is absorbed to the active carbon by passing air flow through openings in the honeycomb, and the absorbed stink ingredient is decomposed by exciting the photocatalyst due to application of the ultraviolet rays.
