| Outline of Final Research Achievements |
Water-sealed dielectric barrier discharge in carbon dioxide under atmospheric pressure affords a carbon fixation pathway to peroxide products such as a performic acid. The chemical mechanisms of the catalyst-free carbon fixation were analyzed by several spectroscopic methods with the aim of improving the efficiency of the selective generation of performic acid. We measured water molecule density in dielectric barrier discharges with a gas-water interface by tunable diode laser absorption spectroscopy. The water molecule density at the gas-water interface has a significant influence on the generation of peroxide products.
