Problems solved by technology

[0005] The process of electrolyzing air to produce ozone produces NO x and other toxic substances, the required AC voltage is high, the electrolysis efficiency is low, it is difficult for ozone to enter the water, the equipment occupies a large area, and the use cost is extremely high
[0006] The efficiency of ozone generated by electrolysis of pure water units is the highest. The electrolysis process uses solid precious metal polymers as electrolytes, combined with cation exchange mode, to obtain ozone through low-voltage electrolysis. However, in this process, the control system is relatively complicated, and the electrolysis efficiency is low. Ozone Difficult to enter the water, high cost of use
Moreover, in the traditional electrolysis device, the cathode and anode materials are all made of metal conductive materials, and some substances in the water body may react with the metal electrodes, which is not suitable for long-term use in strong acid and strong alkali water bodies

Abstract

The invention relates to an ozone generating electrode, a preparation method of the electrode, and an electrolytic device containing the electrode. The electrode is prepared by the following steps: preparing an electrode plate and a catalyst, wherein a non-metallic conductive material is selected as the electrode plate, and the catalyst is prepared by performing a reaction by using SnC2O4, Sb2O3,Ni(CH3COO)<2>.4H2O as raw materials; coating the electrode plate with the catalyst, and heating the electrode plate at temperature of 450-780 DEG C; repeating the above step for 9-14 times to allow the catalyst to form a uniform coating film on the electrode plate; and performing sintering treatment on the electrode plate to obtain the electrode. When the electrode prepared by the method is used as an anode of the electrolytic device, the ozone production is higher in the electrolytic process, the electrode has longer service life, and the electrolysis device can be used for treatment of strong-acid and strong-alkali wastewater.

Description

technical field [0001] The invention relates to the field of electrochemistry, in particular to a preparation method of a novel electrode capable of generating ozone, and provides an electrolysis device containing the electrode. Background technique [0002] Ozone has strong oxidizing properties and is easy to decompose. It can be used as a sewage purifier, decolorizer, disinfectant, etc. When using ozone for sterilization, the speed is fast and the effect is good. Ozone itself is reduced to generate oxygen. Due to the above-mentioned advantages of ozone, its use has been widely recognized, and it is a world-recognized green disinfectant. However, since the half-life of ozone at room temperature is 15-30 minutes (minutes), conventional storage of ozone is difficult and expensive. [0003] At present, the commonly used methods for producing ozone include corona method, electrolysis method, ultraviolet method, and nuclear radiation method. Among them, the equipment investmen...
