CO2 splitting by DBD: understanding the influence of electrical parameters and regimes
Plasma processes are an innovative approach for the decomposition of CO2 in O radicals and CO as a valuable carbon source. In this experimental work, a tubular dielectric barrier discharge operating at atmospheric pressure has been used to split CO2 and study its conversion considering the influence of frequency and power, as well as the influence of various electrical regimes (AC, AC pulsed regimes). The CO2 conversion has been measured by mass spectrometry and gas chromatography while gas and walls temperatures have been determined and correlated to evaluate their influence of the CO2 splitting.
