Abstract
Section titled āAbstractāBDD is a substance which is generated by doping Diborane (B2H6) in CH4 and H2, and then synthesized with thin diamond film. It has good corrosion resistance, is physically and chemically stable, has a wide potential window, low electrical conductivity, good heat impact resistance and optimal hardness, so it is highlighted among electrodes. PbO2, an electrode previously used for generating ozone water, presents environmental problems since the structure of the electrodes is changed and aged due to the strong acidity of the ozone generated when these electrodes are employed for a long time, so it is considered to have short longevity. Moreover, Pb a heavy metal component, is eluted, etc. In contrast, BDD has recently been highlighted as an electrode that can be used for next-generation ozone water generation to solve these problems. Boron-doped diamond electrodes have excellent hardness, excellent physical properties. Chemical stability, and durability. In addition, BDD has a wide potential window and low current density characteristics, so application attention is focused. This study evaluated the ozone-generating characteristics of BDD electrodes generated in accordance with the doping concentration of boron. The BDD generated was examined by field emission scanning electron microscopy and Raman spectroscopy, and its electric characteristics were determined by Hall measurements. The amount of ozone generated at the boron doping concentration was compared using an ozone generating kit. Figure 1
