27 June 2012: Element Six, the world leader in synthetic diamond supermaterials, and academic researchers from the University of Warwick's Departments of Chemistry and Physics, have demonstrated the key factors that determine the electrochemical properties of metal-like boron-doped synthetic diamond. The research shows that boron-doped synthetic diamond has outstanding electrochemical properties while retaining the full strength and durability of its chemical structure. This research opens the possibility of exploiting synthetic diamond's electrochemical technologies in a wide range of applications ranging from sensors to electrocatalysis.
The study's material science findings have been published in Angewandte Chemie Intl. Ed. under the title: Electrochemical Mapping Reveals Direct Correlation between Heterogeneous Electron-Transfer Kinetics and Local Density of States in Diamond Electrodes (DOI: 10.1002/anie.201203057). The paper demonstrates that the material's electrochemistry is determined by its local boron levels and the corresponding density of electronic states. The amount of boron doping in the material, coupled with a reduction in graphitic content to below detectable levels, makes synthetic diamond an ideal material for the study of electrochemical reactions over a wide potential measurement range.
The research was made possible by the high quality boron-doped synthetic diamond samples grown by Element Six through chemical vapour deposition (CVD), and optimised specifically for electrochemical applications. Element Six has a number of patents and patent applications covering its boron-doped synthetic diamond materials suitable for electrochemical applications, part of its portfolio of 600+ granted patents worldwide.
The collaborative research managed to overcome the challenge of creating a synthetic diamond material that is electrochemically active without affecting its chemical structure. The study revealed that it w
