Dissociation of carbon dioxide in atmospheric pressure microchannel plasma devices

Plasma discharge of carbon dioxide at atmospheric pressure was successfully demonstrated in microchannel plasma devices at breakdown voltages lower than 1 kVRMS. Optical emissions of molecular and ionic fragments of carbon dioxide were observed in emission spectra of visible wavelength range measured through a transparent dielectric coated with ITO electrode. Quantitative analysis by mass spectrometry derived the conversion rate of 2.40 ± 0.1 % and the energy efficiency of ~15 %. These results can be improved by modifying the device structures which leads to higher power loading and device packing density.
