Abstract
Csp2 graphite impurities are undesirable in synthetic diamond electrodes Csp3 because they can affect the electrochemical response In this work we demonstrate that Csp3 surfaces can be activated successfully by applying an anodic current density corresponding to sufficiently high potential where the hydroxyl radicals ●OH are generated The effectiveness of this activation process was verified by Raman spectroscopy Xray diffraction scanning electron microscopy and cyclic voltammetryThe authors thank the Mexican Council of Science and Technology CONACyT for the financing granted for the implementation of this study through the Sector Research Fund for Education—Basic Science4955 and the Joint Fund of the State Government of Veracruz Key96313 The authors also thank Dr Luis Miguel Apátiga Castro as well as Dr Eric Rivera Muñoz Dra Genoveva Hernández Padrón and Alicia del Real López from Center for Applied Physics and Advanced Technology CFATA for their support in the characterization of BDD during the different pretreatments Alejandro Medel thanks CONACyT for the fellowship that it granted
