The activity of non-metallic boron-doped diamond electrodes with sub-micron scale heterogeneity and the role of the morphology of sp2 impurities

Abstract:

The electrochemical activity of low boron-doped diamond electrodes prepared by hot filament chemical vapour deposition with varying methane levels in a hydrogen source gas ratio is studied by cyclic voltammetry (CV), Raman spectroscopy and scanning electron microscopy (SEM). The electrochemical response of the electrodes is found to be inconsistent with the electrodes acting as semi-conducting interfaces i.e. no diode like behavior is observable. Hence, on the basis of the presence of sp2 and...
