RIKEN Center for Sustainable Resource Science Biofunctional Catalyst Research Team
Team Leader: Ryuhei Nakamura (D.Sc.)
Research Summary
We work on the development of biologically inspired catalysts and their application to energy conversion and production systems. Specifically, we attempt to exploit the nature’s ingenuities of multielectron catalytic reaction, electron/proton transport, metabolic regulation, flexible response to external stimuli, and the robust energy management in a deep sea environment to develop the novel materials and systems necessary to effectively manage renewable energy sources.
