Nitrogen Fixation Reaction Path in Gas-Liquid Two-Phase Dielectric Barrier Discharge Using Emission Spectra
To study the nitrogen fixation reaction path in micro-channel gas-liquid two-phase dielectric barrier discharge(DBD),we propose a method to determine DBD characteristics using emission spectra.Based on the experimental results obtained for gas-liquid two-phase DBD nitrogen fixation,the characteristic parameters and active particle composition of DBD plasma are derived using the measured emission spectra,facilitating an in-depth analysis of the DBD nitrogen fixation reaction path.The experimental results indicate that the proposed method can accurately determine the vibration temperature,rotation temperature,and active particle composition of N2 during the DBD nitrogen fixation reaction.This approach circumvents the plausible effects of traditional intrusive measurement methods on the nitrogen fixation reaction of DBD.Therefore,this study offers a novel,reliable,and practical method for investigating the gas-liquid two-phase DBD nitrogen fixation reaction path.
