Abstract

The use of porous carbon materials for desalination and water treatment applications has been a heavily studied topic over the last few decades. In particular, the field of capacitive deionization (CDI) has become an increasingly popular method for the desalination of brackish water streams with carbon electrode design and porosity defined as key metrics in addition to operating parameters. In this chapter, carbon xerogel electrodes are reviewed and the effect porosity, surface charge, and the potential of zero charge are highlighted for their impact on the salt adsorption process. Ultimately, all of these parameters predict the desalination performance of a CDI cell, and assessments are made for future electrode needs in this field.
