Outline of Final Research Achievements

In this research, as a first step to synthesize supported ionic liquid catalysts, we aimed to prepare CO2 absorbents by coating the surface of microchannels of silica microhoneycombs (SMHs) with ionic liquid (IL) that bears an amino group. We found that as much as 55 wt % of the IL can be coated on a SMH without clogging its microchannels. The resultant material caused low pressure drop like the original SMH when helium was passed through it and enabled fast CO2 uptake both in bath and flow absorption systems. The prepared absorbent can be reused at least 4 times without loss in performance by regenerating it by heat treatment at 393 K in flowing nitrogen. Collectively, the results show promising properties of the prepared material for CO2 separation.
