| Outline of Final Research Achievements |
The dilute aqueous solution treatment technology applied principle of Electric Double Layer (EDL) is an ion removal process for low environmental burden and energy saving. With more dilute solutions, non-ideal EDL was formed small regions of pore diameter such as a micropore (below 2nm) because of the overlapping effect of diffusion layer.
In this study, Mesoporous carbon nanofilament (CNF) was synthesized by Catalytic Chemical Vapor Deposition process at a relatively mild temperature. Synthesized CNF applied as electrode material of electric double layer capacitor to remove Cs ion dissolved in dilute aqueous. CNF could maintain a high capacitance in dilute aqueous compared with microporous carbon (activated carbon). It was found that the capacitance of CNF per the unit surface area is higher than activated carbon. Mesoporous CNF is suitable for improvement of the rate characteristics of electric double layer capacitor to remove Cs ion dissolved in dilute aqueous.
