Keywords:CO2 reduction, electrocheical system

We are developing an integrated system to recover and enrich CO₂ from the atmosphere, air inside buildings, and exhaust gases from factories, and to convert it into a resource by using renewable electricity. We have been focusing on the design of a reaction field for CO₂ enrichment near the cathode, and have achieved a selectivity of more than 60% for ethylene using nanostructures, mainly Cu, supported on a mesoporous base material. In the future, it is important to design the system as a whole through the concerted development of the elements, including not only CO₂ reduction but also separation and recycling.
