Electronic Supplementary Information: CO2 conversion in a dielectric barrier discharge plasma: N2 in the mix as helping hand or problematic impurity?

摘要: The experimental procedure consists of stabilizing the plasma for 30 minutes, followed by 5 consecutive measurements with the compact gas chromatograph (CGC), which take 2 minutes per measurement, and at the same time recording the peak-to-peak voltage and power, and finally a cool down and flush period of 20 minutes with the next gas mixture. The results shown below are thus the average of these 5 consecutive measurements. All measurements were performed at an applied frequency of 23.5 kHz.
