Our objective is to recycle carbon dioxide, the cause of global warming, and from the preparation of functional CO2 separation membrane, to develop membrane reactors and perform various types of analysis of reaction using CO2 separation.
We advance research from basics to its application in diverse topics within the following groups:

Development of a Functional CO2 Separation Membrane
We develop carrier transport membranes with high CO2 permeation but low permeation of other gasses by introducing chemical compounds that can react selectively with CO2 (CO2 carriers) into polymeric membranes. Currently, our focus is in non-volatile liquid compounds such as Ion-liquids that serve as difussion mediums for absorbed CO2 and CO2 carriers inside the membrane. Our objective is to develop high performance separation membranes appliable in high-pressure gasses through transforming ion liquid into gel film.
Development of CO2 Reforming Processes
We separate and collect high concentrated CO2 generated from thermoelectric plants and iron mills and using it as a resource we develop CO2-reforming reaction processes.
In CO2 reforming, Natural gas and CO2 are made to react, obtaining a synthetized gas (CO2+H2) that becomes a chemical material.
We aim to propose reaction processes for high performance catalysts by performing research related with transitional reaction conditions and operation together with the development of catalysts that reveal chemical properties.
Development of Separation Membrane Functionalizing Catalysts
Through introducing separation membranes into catalysts, we develop catalysts for poisonous materials to not reach active spots. For example, acid spots that become poisoning substances in water.
We perform reaction field water separation, and we aim to obtain solid catalyst reactions in water solvents expected to reduce the environmental load.
