研究実績の概要

In academic year 2019, the in-situ monitoring of reactions taking place under supercritical CO2-subcritical H2O system was extended to other biomass-related materials like sugars and oils and its conversion to useful chemicals such as 5-hydroxymethyl furfural (5-HMF) and biodiesel. Similar to the previous years (AY2018), Raman spectroscopy apparatus using the high-temperature and high-pressure sapphire view cell at Valladolid University was used for the analysis. Collaboration with Prof. Horacio Perez Sanchez of the Bioinformatics and High Performance Computing Research Group of Universidad Catolica San Antonio de Murcia (Spain) to elucidate the mechanism of the hydrolysis by molecular dynamic simulation in order to support the experimental data obtained by Raman spectroscopy gave promising results, and was submitted for publication to a reputable journal in reaction chemistry.

Two graduate students (one under TOBITATE Ryugaku JAPAN Program) was also attached to Wuerzburg University and Valladolid University to study the functionalization of nanodiamond surface and to monitor the reaction mechanism involving the hydrolysis of oils and its conversion to biofuels. Another student from the Philippines worked with me to analyze its application to production of biofuels and obtaining promising results.

理由

In academic year 2019, extended collaboration with the Bioinformatics and High Performance Computing Research Group of Prof. Horacio Perez Sanchez of Universidad Catolica San Antonio de Murcia (Spain) to elucidate the mechanism of the hydrolysis by molecular dynamic simulation to support the data obtained by Raman spectroscopy in Valladolid University gave promising results, and was submitted for publication to a reputable journal in reaction chemistry.

Two more graduate students (one under the TOBITATE Ryugaku Japan) were attached to Wuerzburg University and Valladolid University to study the functionalization of nanodiamond surface and to monitor the reaction mechanism involving the hydrolysis of oils and its conversion to biofuels.

今後の研究の推進方策

The application will be extended to catalytic hydrothermal conversion of CO2 into useful chemicals or fuels by our novel reactive separation approach utilizing the synergy of supercritical CO2 and subcritical H2O. In this research, catalytic reduction of CO2 under hydrothermal conditions into useful compounds such as formic acid and methanol will be elucidated by simply adding the carbon-based catalysts into the system. In the development of catalysts, our nitrogen-doped graphene-based catalysts [Baldovino FH, Quitain AT*, et al., RSC Advances, 6 (2016)] will be compared with a much stable nanodiamond-based catalyst by collaborating with Prof. Anke Krueger of Institute of Organic Chemistry, Wuerzburg University (Germany).
