Electrodes for this process are made of titanium alloys or other metals, and a catalytic layer of platinum group metals, such as palladium, is applied to their surface. This layer accelerates the transformation of sodium chloride from salt into disinfecting hypochlorite.
Nornickel accounts for 42% of the global palladium supply and therefore, together with partners, is working to develop
a new palladium-based catalyst formulation for electrolysis. The innovative water disinfection technology comes with an advantage of not requiring the transport and storage of large stocks of sodium hypochlorite. The disinfectant is formed on site and in exactly the right amount.
By the end of 2023, the company plans to complete the Pd-based catalyst development phase and then proceed to field testing.
