A novel plasma reactor for NO/sub x/ control using photocatalyst and hydrogen peroxide injection

The authors have developed a new type of plasma reactor combining discharge plasma with photocatalyst (TiO/sub 2/) which can improve the performance of NO/sub x/ removal. We also find that hydrogen peroxide (H/sub 2/O/sub 2/) is a very effective additive in this plasma catalytic reactor. NO/sub x/ was effectively oxidized to HNO/sub 3/ on TiO/sub 2/ catalyst and trapped on the catalyst surface. Specific energy consumption of this de-NO/sub x/ process is significantly reduced especially with the injection of H/sub 2/O/sub 2/.
