This paper summarizes experimental results for a method of nitrogen oxides (NO{sub x}) emission control. NO{sub x} was oxidized photocatalytically to nitric acid (HNO{sub 3}) using different titanium dioxide (TiO{sub 2}) catalysts. The addition of ferric oxide improved the performance of the TiO{sub 2}. Of four adsorbents tested, activated carbon performed best in suppressing NO{sub 2} concentration. Optimum catalyst compositions were determined. Initial results indicated that photocatalytic oxidation of NO{sub x} offers several advantages over other emission control methods.
