Typical systems for water electrolysis produces hydrogen on cathode and oxygen on anode. The cathodic hydrogen evolution process has been well developed, whereas the oxygen evolution reaction poses many practical obstacles, mainly resulted from its high overpotential (low energy efficiency) and hazard of H2-O2 mixture explosion. In this regard, replacing water oxidation with ammonia oxidation results in nitrogen evolution on anode. The latter reaction has a very low redox potential, E=-0,06 V vs. RHE. However, the development of ammonia electrooxidation technology is hindered by lack of efficient, cheap, and durable catalysts. Most often currently studied catalysts are based on scarce, expensive metals like Pt and its alloys with noble metals. In this regard, the solution of these problems will boost the development of the vital technologies like ammonia fuel cells, electrochemical treatment of ammonia-rich wastewater, dye sensitized solar cells, and ammonia sensors.

Nickel-based catalysts for electrolytic decomposition of ammonia towards hydrogen production
PublicationNickel is an attractive metal for electrochemical applications because it is abundant, cheap, chemically resilient, and catalytically active towards many reactions. Nickel-based materials (metallic nickel, its alloys, oxides, hydroxides, and composites) have been also considered as promising electrocatalysts for ammonia oxidation. The electrolysis of ammonia aqueous solution results in evolution of gaseous hydrogen and nitrogen....
