The electrochemical reduction behavior of hypochlorite ions (ClO) and hypochlorous acid (HClO) at the surface of boron-doped diamond electrodes is presented. The ClO reduction behavior is strongly affected by the dissolved oxygen through homogeneous oxygen recovery reaction between ClO and H2O2 as ORR product. As for HClO reduction, one-electron mechanism which is a peculiar characteristic of boron-doped diamond electrodes, was observed.
