Abstract
A boron doped synthetic diamond material which has the following characteristics: a solvent window meeting one or both of the following criteria as measured by sweeping a potential of the boron doped synthetic diamond material with respect to a saturated calomel reference electrode in a solution containing only deionized water and 0.1M KNO3 as a supporting electrolyte at pH 6: the solvent window extends over a potential range of at least 4.1 V wherein end points of the potential range for the solvent window are defined when anodic and cathodic current density measured at the boron doped synthetic diamond material reaches 38 mA cm−2; and the solvent window extends over a potential range of at least 3.3 V wherein end points of the potential range for the solvent window are defined when anodic and cathodic current density measured at the boron doped synthetic diamond material reaches 0.4 mA cm−2; a peak-to-peak separation ΔEp (for a macroelectrode) or a quartile potential ΔE3/4_1/4 (for a microelectrode) of no more than 70 mV as measured by sweeping a potential of the boron doped synthetic diamond material at a rate of 100 mV s−1 with respect to a saturated calomel reference electrode…
