Description

technical field

[0001] The invention relates to a preparation method and application of a gold-modified boron-doped diamond electrode. Background technique

[0002] Boron-doped diamond materials have good wear resistance, chemical stability, biocompatibility and some excellent electrochemical properties, such as low background current, wide potential window and surface acid and alkali resistance. Therefore, boron-doped diamond materials have great application potential in the field of electrochemical analysis.

[0003] The existing boron-doped diamond preparation methods are mainly high temperature and high pressure method and chemical vapor deposition method. Most boron-doped diamonds prepared by high temperature and high pressure methods are bulk materials with different sizes, and secondary processing, such as cutting and grinding, is required according to actual needs. Moreover, high-temperature and high-pressure boron-doped diamonds often contain impurities such as ca...
