Abstract

The invention discloses a titanium-based positive plate used for active oxygen preparation and a preparation method thereof. The cleaned titanium sheets are subjected to rhodium-plating treatment to obtain a substance B. The substance B is subjected to modification by mixed liquor prepared by palladium hydroxide and lanthanum hydroxide to obtain a substance D; and the substance D is subjected to modification by the mixed liquor prepared by ammonium borofluoride, sodium hexafluorophosphate, lithium metaborate and cobaltic sodium nitrite to obtain the substance which is the titanium-based positive plate used for active oxygen preparation. The titanium-based positive plate used for active oxygen preparation has the beneficial effects that the prepared titanium-based positive plate used for active oxygen preparation has the characteristics of high activity, strong adaptability and long usage life.

Description

technical field [0001] The invention belongs to the technical field of chemically modified electrodes for wastewater treatment, and in particular relates to a modified titanium-based anode plate for preparing active oxygen and a preparation method thereof. Background technique [0002] Electrocatalytic oxidation technology is to degrade organic pollutants in wastewater by catalyzing the generation of strong oxidizing active oxygen groups such as hydroxyl radicals through the reaction between electrodes. It has the characteristics of no secondary pollution, low cost, strong applicability, and high efficiency. It has application potential in the treatment of high-concentration, biodegradable wastewater. The electrochemical reaction is generally carried out near the surface of the electrode, so the surface performance of the electrode is very important. Selecting a suitable electrode material and modifying it to improve the surface catalytic performance of the electrode has bec...
