The research progresses on production of ozone by dielectric barrier discharge (DBD) plasma at home and abroad are introduced from three aspects such as forms and arrangements of electrodes,feed gases,and dielectric barriers and packed materials.The effects of various factors on the generation of ozone are analyzed.It is indicated that arranging electrodes reasonably and making full use of the synergistic effects of catalysts and packing materials with plasma can increase the conversion rate of oxygen,the ozone concentration and the energy efficiency.
