PURPOSE:To simplify a process and to reduce operation cost by utilizing limitless and clean solar energy, oxidizing to absorb nitrogen monoxide and sulfurous acid gas to recover as sulfate and nitrate. CONSTITUTION:A photocatalyst 3 is obtained by imparting water repellent characteristic on the surface of a photosemiconductor and a photocatalyst structural body supports the photocatalyst 3. The subject device includes an absorbing or oxidizing reactor of sulfurous acid gas, nitrogen monoxide, sulfite or nitrite using the photocatalyst and the photocatalyst structural body together with the process for recovery of the product. |
