| Outline of Final Research Achievements |
We have developed a precise analysis technique for understanding the chemical structure of the graphite edge sites, which was considered to be the most important and difficult in this research project, within the period of this research. This technique makes it possible to distinguish phenol from ether and edge hydrogen on the edge sites by using deuterium labeling. By using this technique, it is possible to evaluate the actual chemical structure of the graphite edge sites, which is expected to make a great leap forward in the future research. Regarding these results, we have published a paper in an international journal and made a patent.
