| Abstract
| - Conversion of NO under UV irradiation was evaluated at310 K in the presence of O2 in a flow-type reactor over AgCl/Al2O3 catalysts calcined at various temperatures. The AgCl/Al2O3 catalysts were highly active for the conversion ofNO. N2O was produced with a small amount of N2 and NO2on the AgCl/Al2O3 catalysts under UV irradiation. The AgCl/Al2O3 catalyst calcined at 673 K where crystallized AgCl co-existed with isolated Ag+ ions showed the best performanceamong catalysts studied. Initial conversion was achievedat 83%. However, the conversion levels of NO on the AgCl/Al2O3 catalysts calcined below 673 K were rapidly loweredwith increased photoirradiation time. High stability forNO conversion was attained on the AgCl/Al2O3 catalystscalcined at 773 and 873 K, where the crystallized AgCl werewell dispersed on Al2O3.
