| Outline of Final Research Achievements |
The photochemical removal of NOx and VOC (benzene, aldehydes) was investigated in N2 or air at atmospheric pressure using a side-on or head-on type vacuum ultraviolet (VUV) excimer lamp. All NOx and VOC gases could be removed after 172 nm VUV irradiation. The decomposition rates of these gases by using side-on type lamp was faster than those by using head-on one. N2O can be decomposed by using a 190 nm excimer lamp under greatly suppression of toxic O3 gas emission. The decomposition of C6H6 by 172 nm lamp was studied and the results obtained were compared with those obtained by model calculations. A reasonable agreement between experimental and model calculations was obtained, leading us to conclude that the O(3P) + C6H6 reaction plays a significant role in the initial stage of the decomposition of C6H6. Not only batch experiments but also flow ones were performed for the practical application of this technique. Many fundamental data for practical application were obtained.
