- Abstract
Carbon dioxide conversion is considered a promising solution to the problem of global warming and the need for renewable energy storage. Although it is challenging to develop a process that combines the complete conversion of CO2 to CO in the absence of O2, this paper describes such a solution. In this study, the CO2 splitting was investigated and monitored in situ using a plasma generated in a DBD reactor without the participation of a catalyst. The results of excited-phase FTIR spectra indicate that gaseous H2, in contrast to Ar, acting as a scavenger of excited CO2 species significantly improves the process efficiency and minimizes the formation of oxygen.
