Characterization of boron doped diamond during oxidation processes: Relationship between electronic structure and electrochemical activity

Abstract

This work investigates the behaviour of BDD samples differently aged by an oxidative treatment. Two series of data are presented: the first in acid solutions was used to derive information about the electronic structure of the samples, whereas measurements in equimolar ferro/ferri cyanide solutions were performed to test the activity of the samples towards charge transfer reaction. Flat band potential as well as energy levels of conduction and valence bands were calculated for new and aged samples. These parameters, together with the current voltage response, are crucial information for a comprehensive interpretation of the behaviour of samples

“…We attribute this to the known change in surface termination from H-type to OH-termination. [30] Runs 7, 11, and 15 were each the first run after the cell was idle overnight during the initial test phase where the interface was open to the air. From previous studies, deposit formation (fouling) is known to occur while electrolysis, and its modification by oxidation may contribute to the observed effect.…”
