Research Outline

Based on a recognition of adsorption phenomena of molecules and ions on surface and in pores, I’m trying to develop high-performance porous materials, especially for porous carbon materials, for the applications in energy and environment related fields, such as for adsorption heat pump systems.

Pore structural model of activated carbons based on recognition of micro-domain

Pore structural model of activated carbons based on recognition of micro-domain

A new concept of ultramicro structural unit (microdomain) based pore structural model of activated carbons was proposed.

Elucidation of adsorption state of ethanol molecule in carbon micropore by solid-state NMR

Elucidation of adsorption state of ethanol molecule in carbon micropore by solid-state NMR

Oriented adsorption state and adsorption inhibition of ethanol molecules in carbon micropores with abundant surface functionalities were confirmed.

Application of newly developed activated carbon to adsorption heat pump

Application of newly developed activated carbon to adsorption heat pump

Activated carbon showing high ethanol adsorbability (1.7 times higher than the conventional one) was successfully developed by adjusting the pore size.
