Abstract

The invention provides a boron-doped diamond film electrode composite substrate. The boron-doped diamond film electrode composite substrate comprises a substrate lower part and a substrate upper part which is positioned on the upper surface of the substrate lower part and is used for depositing a boron-doped diamond film, the lower part of the substrate is a ceramic material, and the upper part of the substrate is a metal material; and a groove is formed in the upper surface of the lower base body part, a protruding part matched with the groove is arranged on the lower surface of the upper base body part, and the groove is used for clamping the protruding part. The protruding part on the upper portion of the base body is clamped in the groove in the lower portion of the base body, the protruding part and the groove are matched with each other, and the bonding performance of the upper portion and the lower portion of the base body made of different materials is enhanced. The upper part of the substrate is a part for depositing the boron-doped diamond film, and the lower part of the substrate is used for providing mechanical support, so that the fluid scouring bearing capability of the substrate is enhanced. The lower part of the substrate is made of a ceramic material, the corrosion resistance is strong, after the boron-doped diamond film is deposited on the upper part of the substrate, the upper part of the substrate with weak corrosion resistance is isolated from fluid by the boron-doped diamond film, the overall corrosion resistance of the composite substrate is improved, and the service life is long.

Description

Technical field [0001] BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to the field of electrochemical electrode, and in particular, a blending diamond membrane electrode composite matrix and a preparation method thereof and a blended diamond thin film electrode. Background technique [0002] In recent years, electrochemical oxidation law has been widely used in the field of organic sewage treatment due to wide treatment, small secondary pollution, and good controllability. When the anode material of the electrochemical oxidation method, the research scholars found that the blending diamond film (BDD) electrode has the widest potential window, extremely high epitope, extremely low background current, extremely chemical inert And anti-pollution poisoning capabilities, very low surface adsorption characteristics, and high electrocatalytic activity, and therefore, the blending diamond thin film electrode has broad application prospects in the field of se...
