Statistical and numerical analysis of secondary electron avalanches with ion-induced electron emission in air

Research on the mechanism of synergistic treatment of VOCs-O 3 by low temperature plasma catalysis technology

“…The utilization rate of ozone in a single low temperature plasma system is very low, and the emission concentration of ozone in the system is high, ranging from 100 to 1000 ppm [4].In order to reduce ozone emissions, the purpose of suppressing the production of ozone and improving the utilisation rate of ozone is generally achieved by using a catalyst. The reaction mechanism of low-temperature plasma is divided into electron avalanche process, particle collision process and energy conversion process [5]. This technology has high removal efficiency of target pollutants, but its shortcomings are reflected in the low energy utilization rate and incomplete degradation of target pollutants, which can easily generate secondary pollutants such as ozone, aerosol, nitrogen oxides, et al [6], it was difficult to apply on a large scale.…”
