Is oxygen cathode technology widely used in chlor-alkali production?
Thread Content
Experts, is oxygen cathode technology widely used in chlor-alkali production? How is this effect? Is no hydrogen produced at all? What material is used for the electrodes?
Oxygen cathode technology is widely used in the chlor-alkali industry; it is an efficient, energy-saving, and environmentally friendly electrolysis technique. Compared with the traditional sodium hydroxide method, oxygen cathode technology does not require the production of hydrogen, which helps to reduce emissions of pollutants such as dust and noise, while also saving energy. The electrode materials used in oxygen cathode technology are generally corrosion-resistant materials such as lead-titanium alloys or platinum-titanium alloys. .
Thank you. I would like to ask again: isn’t the oxygen cathode made of carbon material? I’ve seen in the literature that carbon materials are used for it. :lol
