| Outline of Final Research Achievements |
In the present study, the improvement in the photoelectrochemical production of hypochlorous acid and hypobromous acid was successfully achieved. Both hypochlorous acid and hypobromous acid were produced from sea water by irradiating the photoanode with applying non-external bias, by using Pt/C cathode with gas diffusion layer and one-room electrolysis cell. When Ni2+ was added to the electrolyte solution, the produced hypochlorous acid on the photoanode oxidized it to Ni3+, and then NiO(OH)-like compound was formed on cathode by the electrodeposition. NiO(OH)-like electrode, which were fabricated by oxidative electrodeposition method, was active electrocatalyst for electrocatalytic H2O oxidation and urea oxidation.

| Academic Significance and Societal Importance of the Research Achievements |
本研究は太陽光に多く含まれる可視光で駆動する人工光合成反応を用いて,太陽光から獲得した化学エネルギー（HClO）を直ちにオキシ水酸化物へ変換して蓄積するものであり，太陽光の有効利用方法として非常に有望である。再生可能エネルギーの有効利用を可能とするシーズの一つとするべく、「シンプルな仕組みで有用化合物を創り出す」点を重視して研究を行った。
