Cathode catalyst and cathode structure of membrane electrode electrolysis ozone generator

Abstract

The invention discloses a cathode catalyst and a cathode structure for a membrane electrode electrolysis ozonator. A ferroalloy containing Mo, Cr, Ni is adopted as the cathode catalyst; the ferroalloy is further processed into a ferroalloy net and directly serves as the cathode structure of the membrane electrode; compared with the prior art, the invention selects acid-proof and cheap ferroalloy net as the catalyst and also serves as a micro-porous current-conducting plate, the cathode catalyst and the micro-porous current-conducting plate are integrated into a whole, the invention is novel in the field either in material or structure; the cathode catalyst and the cathode structure for the membrane electrode electrolysis ozonator has the significant advantages that the cathode catalyzing effect is good, the cathode structure is simple, the cost is reduced greatly and the economic benefit is remarkable.

Description

technical field [0001] The invention relates to a cathode catalyst and cathode structure of a membrane electrode electrolysis ozone generator, belonging to the field of electrochemistry. Background technique [0002] The application of ozone has entered a wide range of fields. Membrane electrode electrolytic ozone generators use pure water as raw material, and electrolyze water to generate hydrogen, oxygen and ozone. Because the raw material is pure water, the electrolytic products are pure hydrogen, oxygen and ozone, and there is no possibility of harmful substances such as nitrogen oxides. The special advantage of the membrane electrode electrolytic ozone generator is being paid attention to, and its application field is gradually increasing. big. [0003] The core of the electrolytic ozone generator is the membrane electrode. The structure of the membrane electrode includes: an ion exchange membrane 1, a cathode catalyst 2 placed on both sides of the ion exchange membran...

AI Technical Summary

Problems solved by technology

[0010] The disadvantages of the above-mentioned several cathode structures have two aspects: one, the commonly used cathode catalyst platinum, palladium, rhodium precious metals are expensive; two, the manufacturing process is complicated, and it is difficult to guarantee the quality in production

The shortcomings of these two aspects lead to the high cost of membrane electrodes, which seriously affects the commercialization process of membrane electrode electrolytic ozone generators.
