Outline of Final Research Achievements

In order to improve the functions of the "boron-doped diamond (BDD) electrodes", we have developed a highly functional "innovative sp3 functional electrode material". Here, in the present work, we have developed a boron-doped silicon carbide (SiC) electrode and a high-performance diamond electrodes. For example, in sp3 BDD electrodes, the effects of important parameters such as the containing sp2 carbon species and the boron concentration were investigated in detail to investigate their contribution to the electrochemical properties. Especially, we have studied those factors for the electrochemical CO2 reduction reaction.
