The objective of this research is to accelerate the development of materials and devices that enable carbon dioxide to be converted into a resource by utilizing AI and experimental data. A next-generation proton-conducting solid oxide-type electrolytic cell using carbon dioxide-tolerant Sc-substituted barium zirconate (Adv. Energy Mater. 2020), which has been successfully developed by the representative, as an electrolyte will be constructed to achieve carbon dioxide recycling and selective production of olefin, a high value-added resin material. For efficient development, the machine learning model for proton conductors (ACS Energy Lett. 2021) will be extended to the other materials and their hetero interfaces. Taking advantage of the broad perspectives of the Kyushu University Platform of Inter-/Transdisciplinary Energy Research, the reactions will be evaluated based on the nano-level to device systems and economics. The project is expected to contribute significantly to the realization of “decarbonization” and the “carbon neutral society of 2050” that Japan is aiming for.
The originality of this research lies in the accelerated development of material devices that enable carbon dioxide to be recycled and propylene to be produced simultaneously through the utilization of AI and experimental data. It is also unique that the research is not limited to scientific and technological development but also considers the socioeconomic aspects of the technology.

We will demonstrate CO2 reduction and propane(C3H8) dehydrogenation (propylene(C3H6) production) with high selectivity beyond the equilibrium yield of conventional heterogeneous catalysts by combining an electrochemical cell using a proton-conducting electrolyte (Adv. Energy Mater. 2020), catalysts, and the electrochemical potential. This module will contribute to solving the social issue of achieving Japan’s CO2 emission reduction target (46% of the FY2013 level by FY2030) by integrating the comprehensive knowledge of the researchers at Kyushu university.
