An electrocatalytic desalination system with a solar panel was examined in this study. The system reactor consists of ion exchange membranes for desalination, an TiO2(Ti/IrxTa1–xOy/nano-TiO2) anode, and an Bi-foam cathode. Reactive chlorine species (RCS) is formed from chloride (Cl-) ion in electrolyte by anodic reactions of the TiO2 anode, and the Bi-foam cathode conducts highly selective cathodic reaction making formic acid on the condition of dissolved CO2 gas. Desalination, water treatment and formate production were simultaneously achieved with the system wired to an solar panel. In the electrocatalytic remediation of urea (in urine) as a model water pollutant, TiO2 electrodes converted chloride into RCSs that efficiently mediate the urea oxidation. The catholyte is found to be used as a CO2 capturing solution in which formate as a value-added chemical is simultaneously produced at a high Faradaic efficiency. |
