In this method, sodium chloride—one of the most abundant salts contributing to water salinity—is selectively removed, while energy is generated during the system’s recovery process to power various LEDs. This process is achieved using nanomaterials.

The capacitive deionization method is an electrochemical process used for water desalination, removing salts and various contaminants in ionic form. In this technique, pollutants in the form of ions accumulate on electrodes within an electrochemical supercapacitor cell when a potential is applied.

Recently, alongside its desalination capability, this method has been enhanced to produce energy by recovering the ions accumulated on the supercapacitors during the desorption cycle. This approach is recognized as an efficient and cost-effective method for water desalination globally and provides a novel solution to address today’s water and energy crises.In this regard, researchers from the Department of Chemistry at Sharif University of Technology have designed an innovative system with extraordinary dual-functionality.

The system efficiently purifies water by selectively removing sodium chloride—the most prevalent salt causing water salinity—while simultaneously generating the energy required to illuminate various LEDs during the system’s recovery phase.

Specially synthesized nanomaterials, combined with the unique design of this system, enable energy production from saline water. Additionally, the system’s cost-effectiveness and eco-friendly nature make it a promising technology. These distinctive features set this innovation apart, offering a sustainable solution for water purification and energy generation.
