  • Patent number: 11629073
    Abstract: The present invention relates to a hybrid system for water treatment, desalination, and chemical production. The hybrid system of the present invention includes a photoanode, an anode chamber, an anion exchange membrane, a middle chamber, a cation exchange membrane, a cathode chamber, and a cathode. In the middle chamber, saltwater or seawater is desalinated by photoelectrochemical electrodialysis. Chloride ions are generated during the desalination, transferred to the anode chamber, and activated by the photoanode. In the anode chamber, wastewater is treated by the activated chloride ions. In the cathode chamber, at least one chemical species selected from the group consisting of water, oxygen, and carbon dioxide is reduced by electrons supplied from the photoanode.

  • Patent number: 6559373
    Abstract: The present invention relates to a solar powered cathodic protection system using a photocatalyst which functions as a non-sacrificial photoanode under sunlight, wherein said non-sacrificial photoanode consisting of the photocatalyst such as TiO2 (or ZnO) and an electrolyte, is galvanically connected to a metal structure to be protected and continuously provides electrons to the metal structure, whereby the metal structure is protected from the corrosion. The solar powered cathodic protection system using a non-sacrificial photoanode according to present invention is advantageous in that 1) an external power supply is not necessary, 2) it is easy to maintain the system because the non-sacrificial photoanode according to the present invention can be installed outdoors, and 3) the photocatalyst used as the non-sacrificial photoanode is inexpensive and semipermanent.
