Abstract :
The authors have developed a new type of plasma reactor combining discharge plasma with photocatalyst (TiO2) which can improve the performance of NOx removal. We also find that hydrogen peroxide (H2O2) is a very effective additive in this plasma catalytic reactor. NOx was effectively oxidized to HNO3 on TiO2 catalyst and trapped on the catalyst surface. Specific energy consumption of this de-NOx process is significantly reduced especially with the injection of H2O2
