| Outline of Final Research Achievements |
Electrochemical reduction of carbon dioxide (CO2) to C1 feedstocks (e.g., carbon monoxide (CO)) is receiving a great deal of attention because this proton-coupled electron-transfer (PCET) reaction is responsible for the chemical fixation of CO2 in various types of sustainable energy technologies that utilize solar energy. We have successfully synthesized rhenium(I) complexes, which is a well-known catalyst for the reduction, but this time possessing second coordination sphere wherein imidazolium moieties are arranged so as to interact with a metallo-carboxylate intermediate involved during the catalytic cycle. These complexes exhibited the notable catalytic activities at lower overpotential (ca. 0.3 V) compared with that of the parent rhenium(I) complex.
