A water-energy nexus technology is presented that combines the photoelectrocatalytic (PEC) desalination of saline water and desalination-driven wastewater remediation coupled with the production of H2 from water. Upon irradiation by simulated sunlight, the photogeneration of charge carriers initiates the transport of chloride and sodium in the middle cell to the anode and cathode cells, respectively, leading to the desalination of saline water. The chloride in the anode cell is converted to reactive chlorine species, which effectively decompose urea to N2 as a primary product, while the sodium in the cathode cell accelerates the H2 production from water with a Faradaic efficiency of ~80%. This research was supported by the Basic Science Research Program (2019R1A2C2002602 and 2018R1A6A1A03024962) and the Technology Development Program to Solve Climate Changes (2019M1A2A2065616) through the National Research Foundation, Korea. |
