Ammonia is receiving increasing interest as a carbon-free renewable energy storage medium. Scientific challenges remain to efficiently produce NH₃ by fixing atmospheric N₂ using renewable energy and hydrogen as well as utilizing the energy stored in NH₃. One way the to release the energy stored in NH₃ is electrolysis to produce N₂ and H₂, where the evolved H₂ can be used in a fuel cell. The electrolysis of NH₃ is currently limited by the nitrogen evolution reaction (NER) at the anode. While there have been numerous reports on heterogeneous catalysts for electrocatalytic oxidation of NH₃, with limited success, homogenous molecular catalysts are non-existent. In this talk, transition metal complexes will be presented which show the first examples of catalytic activity in presence of ammonia at room temperature and ambient pressure. We will show the catalytic activity can be modulated via ligand design. Gas chromatography measurements reveals production of N₂ and H₂ in approximately 1:3 ratio following bulk electrolysis of ammonia showing stable catalysis and high faradaic efficiencies. Results from absorption spectroscopy, NMR and various electrochemical measurements will be presented which elucidate the key steps of the catalytic cycle. These assignments will be supported with N isotope labeling experiments followed with Mass Spectroscopy. In addition, spectroscopic and electrochemical measurements of proposed intermediate species in formation of the N-N bond will be presented. From these combined results, a tentative mechanism of the catalytic cycle will be proposed and the implications discussed.
