Outline of Final Research Achievements

In this project, we investigated a method to realize a selective and efficient CO2 protonation reaction by taking into account both acid-base and oxidation-reduction reactions on hydrated oxide surfaces. We employed both experiment and theoretical approaches: The former revealed electrochemical reaction characteristics using single cell experiments on the preferential adsorption of CO2 utilizing surface proton activity and electrochemical reduction via protonation. The latter revealed the origin of proton activities on the hydrated surface that the difference in acid constant between two acid-base sites and the mechanism of proton migration. From the single cell experiments, we examined catalytic electrodes with a controlled dimensionality of reaction sites and the preferential reduction reaction of CO2 but end up with the predominant hydrogen gas formation owing to its low overpotential.
