Abstract
Dye-sensitized ion-pumping membranes and methods of preparing said membranes are described herein. A regenerative and reversible photoactive dye is covalently-bonded to membrane or separator for ion-pumping. The photoactive dye-functionalized membranes can be arranged with other ion-exchange membranes, which serve as selective contacts to afford photovoltaic action and therefore form a power-producing membrane that pumps ions for use in driving an ion-exchange or ion-transport process, such as desalination and electrodialysis.
