Effects of TiO2 coating on zeolite particles for NO and SO2 removal by dielectric barrier discharge process

This Figure shows the comparison of SO2 removal efficiencies by the dielectric barrier discharge-catalyst (DBD-C) and the dielectric barrier discharge-catalyst-photocatalyst (DBD-C-P) hybrid processes for various initial concentrations of SO2. By the combined effects of plasmas, catalyst and photocatalyst, the SO2 removal efficiencies in DBD-C-P hybrid process are higher than those in DBD-C hybrid process by 3-15% for these process conditions.
