ELECTROCATALYTIC MATERIALS FOR ELECTROLYSIS OF CHLORIDE SOLUTIONS

Project Description: Cathode multicomponent electrocatalysts include a steel base with a galvanized coating based on a Co-Mo alloy alloyed with sulfur and phosphorus, with a thickness of 1-2 microns. Anodic electrocatalysts include a titanium base with a pyrolytic active coating based on _Co3O4 with a reduced content of noble metal oxide (1-3%).

The use of the developed electrocatalysts in the electrolysis of chloride solutions makes it possible to reduce the consumption of non-ferrous metals (when replacing the cathode from metallurgical nickel), the consumption of noble metal oxides (when replacing the oxide-ruthenium-titanium anode), and also to reduce the energy consumption for the production of hydrogen and disinfecting solutions.

Advantages: Specific energy consumption for NaClO production is 1.8 times lower, and for hydrogen production is 15-20% lower in comparison with analogs.
