Water treatment

Capacitive deionization (CDI) is an emerging desalination technology. In low molar concentration electrolytes, such as brackish water, CDI promises the combination of low energy consumption and performance stability. CDI employs nanoporous carbon electrodes, but novel approaches include the use of Faradaic materials. Thereby, the desalination capacity can be fully extended to seawater and hypersaline media. Our team explores CDI, hybrid CDI, flow-electrode CDI, membrane CDI, and CDI in non-aqueous media.
