Abstract
Capacitive deionization (CDI), as a novel, energy-efficient, and environment-friendly
desalination technology, has received substantial attention in the scientific community during the last
five decades, while the electrode materials, acting as the ion storage media, play a vital role during
its desalination process. Meanwhile, developing electrode materials from biomass has been proven to
be a feasible strategy due to their abundance in nature, unique microstructure, as well as feasibility
for further modifications. In this review, various bio-mass-based electrode materials and their unique
advantages as CDI electrodes are systematically presented.
Keywords:
Capacitive deionization, electrosorption, desalination, bio-mass derived carbon, electrode material, activated carbon, water purification.
