Advances in Ti/B doped diamond functional coated electrodes and electrochemical oxidation applications

The Ti/B-doped diamond (Ti/BDD) coated electrode exhibits various advantages, including a wide potential window, a high oxygen precipitation potential, high stability, and the low cost. Hence, it has been an optimal choice for industrial applications. In this paper, research results on Ti/BDD coated electrodes in a few years are completely reviewed. The preparation method and B-doping technology of Ti/BDD coated electrodes are also introduced. The current research status of coated electrodes is summarized. A detailed review of Ti/BDD coated electrodes is carried out from the following aspects: substrate types, TiC interlayers, the electrode stability, and the electrochemical oxidation performance. The deficiencies in the research and future development of coated electrodes are pointed out. This review could provide theoretical bases and reference for the related research, promoting engineering application of Ti/BDD heterogeneous material connection.
