In the water electrolysis, the oxygen evolution reaction (OER) is a rate-limiting reaction of the entire reaction and exhibits a high overvoltage. This limitation can be overcome with a rather low overvoltage chlorine evolution reaction (CER). Based on this, we developed a thermochemically reduced TiO2 material that generates reactive chlorine species via photoelectrocatalytic oxidation in an electrolyte containing chlorine ions. The reactive chlorine species generated by the chlorine evolution reaction conducted water treatment by decomposing urea contained in the electrolyte. In addition, it was confirmed that desalination, hydrogen production, and water treatment function at the same time by constructing an electrodialysis type seawater desalination device independently driven by sunlight together with a nickel-molybdenum-sulfur (Ni2S3/MoS2) complex electrocatalyst, facilitating hydrogen evolution reaction. |
