A novel carbon dioxide capture technology from the atmosphere using inexpensive and safe carbon dioxide absorption materials.
Keywords: Carbon dioxide separation and recovery, carbon dioxide emission reduction, effective utilization of carbon dioxide.
In order to achieve carbon neutrality, research and development of carbon dioxide capture technology, which is considered one of the factors contributing to global warming, is progressing. Chemical adsorption methods are one of the capture technologies, and the conventional method of chemical absorption of carbon dioxide using amine compounds has been limited in application due to issues such as volatility, toxicity, and corrosiveness unique to organic compounds. In our laboratory, we have discovered that materials made from unprecedentedly inexpensive raw materials (sodium, iron, oxygen) can separate and capture carbon dioxide from mixed gases in the atmosphere over a wide temperature range and at various concentrations. Currently, we are working on improving the absorption rate of carbon dioxide, developing regeneration technology, and promoting the effective utilization of captured carbon dioxide. Additionally, we have successfully identified novel inorganic solid oxides that possess superior functionality for capturing carbon dioxide from the atmosphere compared to sodium ferrite, and we are advancing the development of new materials that are optimal for the application environment of carbon dioxide absorption materials.
