Research Projects

• Investigation of chemical structure of graphite edge sites maximizing its performance for Li secondary battery, Ishii Takafumi, Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Early-Career Scientists, Grant-in-Aid for Early-Career Scientists, Gunma University, 01 Apr. 2018, 31 Mar. 2020, 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., 18K14312

• Development of carbon alloy cathode materials realizing the simultaneous power generation and organic synthesis, Ozaki Jun-ichi, Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Scientific Research (C), Grant-in-Aid for Scientific Research (C), Gunma University, 01 Apr. 2015, 31 Mar. 2018, This research was aimed at the development of two types of carbon alloy catalysts necessary for constructing the system shown in the title. As for the preparation of the first type catalyts, we prepared carbon materials from mixtures of a starting polymer and different types of transition metal complexs and evaluated the hydrogen peroxide formation. The second type catalysts were the heteropolyacid (HPA) fixed on the carbon alloys with surface basicity. We conducted the characterization and activity test using 3-methyl -3-buten-1-ol as the reactant to be oxidezed by hydrogen peroxide. We found the possibilities to control the electronic state and the catalytic activity of HPA by tuning the surface properties of the carbon substrates., 15K00600
