The Ecomaterial Science Laboratory, staffed by researchers of the Research Institute of Innovative Technology for the Earth (RITE), provides research and education on fundamental technologies to solve the global warming issues. We endeavor to develop advanced materials for CO2 capture and inorganic membranes for H2 energy production. Specifically, solid materials (e.g. zeolite, mesoporous silica, MOF) have been investigated in order to reduce the energy requirements and cost for CO2 capture. Concerning CO2-free, H2-based energy systems generated by any renewable sources, it is necessary to develop efficient processes for the dehydrogenation of chemical hydrides such as methylcyclohexane or ammonia. We evaluate silica, zeolite and palladium membranes for the processing of chemical hydrides.

In our laboratory, we normally provide our students with OJT (on-the-job training) education through the projects conducted in RITE. The students can deepen their understanding of social contexts, causes and countermeasures concerning global environmental issues. They also learn fundamental knowledge of material science in relevant subjects such as physical chemistry, organic/inorganic chemistry, synthesis, and chemical engineering.
