Membranes for electrochemical technologies that operate at non-extreme acidic or basic conditions are described herein. The membrane can be a bipolar membrane having an anion-exchange layer, a cation-exchange layer, and a polymer layer containing a catalyst juxtaposed between the two layers. The catalyst can improve the rate for water dissociation and water formation at low applied bias thereby decreasing the overpotential and resistance for overall ion transport, especially when unequal pH values are used between the catholyte and anolyte.

Membranes for enhancing rates of water dissociation and water formation

A photodialysis device that can desalinate saline streams is described herein. The device can have a desalination rate that is significantly faster than current solar thermal desalination technology. Salt is removed from water by passing ionic current derived from sunlight through this water using dye-sensitized membranes. The device can serve as a distributed, low-cost technology that can efficiently and effectively desalinate low salinity sources of water, which is particularly useful for agriculture and drinking water applications.
