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.
