Implication

New cross sections improve understanding of CO2 dissociation rates in mixtures, indicating changes in electron energy distribution.

Key Points

The aim is to provide updated electron-impact cross sections for CO2 that accurately reflect dissociation processes and their applications in mixtures.
Developed electron-impact cross sections for CO2 based on energy thresholds and dissociation pathways.
Validated results using experimental data on dissociation rate coefficients and CO2 conversion efficiencies.
Analyzed electron transport coefficients across a range of electric fields in CO2-Ar and CO2-N2 mixtures.
The updated cross sections demonstrate completeness and consistency across various electric fields.
Significant changes in the electron energy distribution function are observed in CO2 mixtures with Argon and Nitrogen.
Revealed varying CO2 dissociation rate coefficients depending on the composition of the gas mixtures.
