Chemical modification of activated carbon for high performance capacitive deionization cells |
| 초록 |
Capacitive deionization (CDI) is electrochemical process which is considered as a promising desalination technology. This new growing CDI technology needs to overcome the following: 1. low performance electrodes 2. short lifetime 3. low energy and cost-effectiveness. The efficiency and kinetics of the continuous salt removal process via CDI can be improved significantly by optimizing electrodes without using less common or highly elaborate novel materials. In this study, we attempted to develop high performance electrodes via introduction of ion-exchangeable groups on activated carbon. This led to the spontaneous attraction of counter-ions to electrodes of CDI cell during ion-sorption step. The noble carbon electrodes-based CDI cell exhibited significantly enhanced performances compared to the activated carbon-based CDI cell. The experimental results will be presented in detail. |
