| Outline of Final Research Achievements |
The present study focuses on the enhancement of electrochemical reactions in nanoporous electrodes. We have studied especially from the viewpoint of mass-transport of ions in nanopores. Nanoporous silicon electrodes were utilized as the prototype porous electrode, and metal electrodeposition was conducted using the porous electrode. In platinum electrodeposition, we have revealed that the penetration of platinum complex anions were accelerated when using micropore, together with the accumulation of the ions in the confined nanopore. Such accelerated penetration was observed not only in platinum electrodeposition but also in other deposition systems and in electrolyte without metal ions. Thus, it was concluded that the accumulation and acceleration of ions in nanopore was generally achievable by choosing the appropriate pore size and charge density of ions. This conclusion is highly important for further precise control of electrochemical reactions in nanoporous electrodes.
