•Observation of the first reduction stage of HClO at a BDD electrode•The observation of a one-electron reduction is peculiar to BDD.•Characteristic as nonactive electrode allows to observe of one-electron reduction.•ClO− is considered as product of one-electron reduction of two HClO.•ClO− reduction proceeds through ORR by chemical reaction with H2O2.
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.
