Title:
NOVEL ANODE MATERIAL AND PREPARATION METHOD THEREFOR, AND DEVICE FOR GENERATING OZONE BY ELECTROLYSIS
Document Type and Number:
WIPO Patent Application WO/2019/149142
Kind Code:
A1
Abstract:
The present invention relates to a novel anode material and a preparation method therefor, and a device for generating ozone by electrolysis. The anode material is prepared by: adding 500-1500 parts by weight of SnC2O4 to a reaction kettle, and adding at least 150 parts by weight of water and stirring uniformly; adding 5-8 parts by weight of Sb2O3 to the reaction kettle, and stirring and heating the solution for uniform mixing, to obtain a mixture; adding 1-3 parts by weight of Ni(CH3COO)2·4H2O to the mixture, introducing oxygen into the reaction kettle, heating and stirring the mixture until the materials in the kettle are in a suspended state, then stopping heating, precipitating the materials in the reaction kettle, and extracting the upper layer suspension after completion of precipitation, to give a Sn-containing suspension; coating the Sn-containing suspension on an anode plate, carrying out pyrolysis at a temperature of 400-600°C, and repeating the coating-pyrolysis process 7 to 9 times to form a coating film; and sintering the coating film at a temperature of 500-650°C for 60-120 minutes. The method for preparing the anode material of the present invention is simple and easy to operate, and produces no toxic and harmful substances when used for ozone production.
