Preparation methods of boron-doped diamond electrode and its research progresses

Abstract

The common two-dimensional boron doped diamond flat plate electrode in the practical wastewater treatment application shows the disadvantages of small reactive area and low degradation efficiency. In order to realize excellent degradation efficiency towards wastewater, it is expected that boron doped diamond electrode has high specific surface area so as to enhance the reactive area and has special surface structure so as to enhance its oxidative and catalytic ability. However, there still exists problems such as the complexity of preparation process and expensive equipment for such boron-doped diamond electrode. In order to address above problem, this article focuses on the preparation methods of the boron doped diamond electrode, analyze the merits and demerit of these methods, and discusses its industrial application prospect in wastewater treatment.
