The electrochemical properties of boron doped diamond (BDD) electrodes were studied using voltammetric techniques. Electrodes with different boron doping level ranging from 500 ppm to 8000 ppm (B/C ratio during BDD deposition) were characterized by cyclic voltammetry of inner- and outer-sphere redox markers.
Furthermore, attention was paid to the influence of boron content on the voltammetric responses of phenol derivatives on BDD electrodes activated by anodic oxidation of the surface. In general, the peak potential of oxidation of phenolic compounds shifts towards more positive potential with decreasing boron content.
