Abstract

The electrochemical decomposition of CO2 into its elemental forms through CO2 and CO2-Ar microwave induced plasmas is studied via optical emission spectroscopy. The active species present as well as the electrochemical processes that produce them have been identified. It has been shown that the microwave plasma device was able to achieve CO2 decomposition with the existence of CO and C species. The optimum power for CO2 conversion was determined from a set of powers used for CO2 and CO2-Ar plasmas. It has also been shown that the addition of argon improved CO2 decomposition.
