Controlled Anodic Treatments on Boron-Doped Diamond Electrodes Monitored by Contact Angle Measurements

In Situ ATR-IR Observation of the Electrochemical Oxidation of a Polycrystalline Boron-Doped Diamond Electrode in Acidic Solutions

“…The appearance potentials of ν CO and ν C–O on BDD are consistent with the formation potential of oxygen species evaluated by ex situ C 1s XPS spectra. , The wettability on electrochemical oxidized BDD was investigated by contact angle measurements. , The contact angle of water on hydrogen-terminated BDD decreases with successive electrochemical anodization, which correlates with the appearance potentials and band intensities of ν CO and ν C–O observed in this ATR-IR study.…”

“…24,25 The wettability on electrochemical oxidized BDD was investigated by contact angle measurements. 24,29 The contact angle of water on hydrogen-terminated BDD decreases with successive electrochemical anodization, which correlates with the appearance potentials and band intensities of ν CO and ν C−O observed in this ATR-IR study.…”

Electroless oxidation of diamond surfaces in ceric and ferricyanide solutions: An easy way to produce “C–O” functional groups

“…Even if as-deposited hydrogen terminations are highly stable [7][8][9], it can be converted to oxygen terminations, either by dry or by wet techniques. For example, interesting preconditioning of the diamond surface can be reached either by O 2 plasma [2][3][4][5][6][7][8][9][10], UV-ozone photochemical treatment [11], chemical oxidation at T = 200 • C in a mixture of pure nitric and sulfuric acid (1:3) for 2 h [9,12] or by anodic polarization in acidic solution [13][14][15][16][17].…”

ZnO Electrodeposition on Boron-Doped Diamond: Effects of Diamond Surface Terminations

“…In the present work, we focus on the influence of the BDD surface chemistry either H-or O-terminated obtained by different oxidation treatments (electroless (12,13)) or anodic (14,15)) on the ZnO deposition process. Surface terminations are followed XPS analyses.…”
