| Outline of Final Research Achievements |
In this work, we focused on electrochemical reduction using CO2 and seawater as starting chemicals and solar light as an energy to produce useful organic chemicals. We actually used conductive diamond as an electrode, seawater as an electrolyte, and solar cell or photocatalyst as photo-energy conversion materials. Furthermore, we obtained below results: (1) Amine modified diamond electrode showed higher yield production of formic acid. (2) Optimum concentration of NaCl as a electrolyte is 3% for electrochemical reduction to produce useful chemicals. (3) We constructed a system comprising diamond electrode and GaN electrode as a photocatalyst.
