Triple Product Overall Water Splitting – An Environment Friendly and New Direction Water Splitting in Sea‐Water Mimicking Electrolyte

Hydrogen production is highly desirable which is well‐organized water‐electrolysis system using sea‐water, but it is a big challenge to manage it by the use of conventional catalysts. The present study demonstrates the efficient triple‐product water‐electrolysis system, which operates for >100 h in highly chloride containing alkaline electrolyte (6 M NaOH with saturated NaCl). While sea‐water exhibits salinity of ∼3.5 %, where Cl− followed by Na+ is predominant specie. The water electrolysis system with nafion membrane also produces triple product. The water‐electrolysis system produces environmentally friendly triple product using NiMo as cathode and NiFe LDH as anode such as H2, O2, and crystalline NaCl.
