Enhanced Decomposition Of Cf_4 In Atmospheric-pressure Nonthermal Nitrogen Plasmas By Pulsed-electron-beam Pumping

摘要

The decomposition of CF_4 using pulsed-electron-beam-generated atmospheric-pressure nonthermal nitrogen plasmas (CF_4 900 ppm, 130 kPa) is demonstrated. A high energy efficiency was obtained in the destruction and removal of CF_4 compared with the results obtained using dielectric-barrier-discharge plasmas. The results are mainly attributed to the enhanced decomposition of CF4 by nitrogen ions that are efficiently generated by high-energy electron beams. The scavenging of reactive intermediates from the plasma without producing hydrogen fluoride is also attempted and its validity is discussed.
