| Outline of Annual Research Achievements |
Due to coronavirus-related pandemic, mobility of researchers and students was not possible this academic year. However, the following research-related and academic activities were carried out with Valladolid University. ① Mobility of an alumnus from Kumamoto University, under the Marie-Curie Individual Fellowship Program (Research Title: "Cascade Hydrolytic Recovery and Conversion of Suberin in High Pressure Media."). She was a doctoral student under the supervision of Prof. T Kida and Prof. AT Quitain. She will carry out research related to biomass utilization using microwave and supercritical fluid technologies in Valladolid University for 2 years starting October 2020.②Online lecture by Prof. MJ Cocero on“Perspectives on Biomass Utilization”, being offered at the Center for International Education and participated by a total of about 180 undergraduate students from Kumamoto University and Sepuluh Nopember Institute of Technology (ITS, Indonesia). ③Publication of a joint article in reputable journal in this field: “Supercritical CO2-subcritical H2O system: A green reactive separation medium for selective conversion of glucose to 5-hydroxymethylfurfural” that consolidates previous research outcomes of Prof. AT Quitain and his students in Valladolid University.
Experiments on nanodiamond provided by Prof. Anke Krueger of Wuerzburg University on CO2 reduction and sugar conversion to useful chemicals and fuels were also carried out here in Kumamoto University.

Current Status of Research Progress
3: Progress in research has been slightly delayed.
Reason
Due to corona virus-related pandemic, mobility of researcher and students was not possible this year.

| Strategy for Future Research Activity |
The application of nanodiamond on catalytic hydrothermal conversion of CO2 into useful chemicals or fuels will be further investigated utilizing the synergy of supercritical CO2 and subcritical H2O. Catalytic reduction of CO2 under hydrothermal conditions into useful compounds such as formic acid and methanol will be further elucidated by simply adding the carbon-based catalysts into the
system. Nanodiamond will be compared with our graphene oxide-based catalysts. If the pandemic situation gets better, the principal investigator will visit Wuerzburg University to functionalize carbon-based catalysts to improved yields of target materials - low molecular weight carboxylic acids and alcohols. The work on sugar conversion into useful chemicals will also be further investigated.
