Sustainable graphene-based nanocomposites for water desalination using capacitive deionization technology

Fresh water for human daily life is an important resource in the world. Currently, more than one billion people around the world are suffering from a shortage of clean fresh water and its adverse consequences on health, food and energy. The present population growth, increased industrialization, greater energy needs, loss of snowmelt and shrinkage of glaciers will dramatically worsen this situation in coming years. A key technology that could mitigate this serious problem is the development of cheap, long-term stable and effective systems for combined seawater desalination and purification. The scientific aims of this project are to develop a fundamental understanding of the complex electrochemical processes present in graphene/metal oxide nanocomposites and to design optimized long-term stable and regenerable nanocomposite electrodes for desalination and ion purification of seawater.
