Ammonia Synthesis from Water and Nitrogen Under Ambient Condition Using Single Atom Nickel

Shreya MukherjeeGang Wu

Our dependence on ammonia is not limited to development of fertilizers and other chemicals. Ammonia is being considered an energy vector, capable of being used for energy storage as well as fuel, due to its high energy density, ease of storage and transportation. Growing need for ammonia has forced development of alternate strategies for synthesis worldwide to serve as back up of Haber Bosch. Electrochemical ammonia synthesis is one such alternative. Earlier, we found that, nitrogen vacancy in metal-organic framework-derived disordered carbon is active for nitrogen reduction in alkaline electrolytes. We tried to investigate Fe-N4 sites for nitrogen reduction. It…

Electrochemical Synthesis of Ammonia Using Nitrogen and Water in Alkaline Electrolytes Under Ambient Conditions

Shreya MukherjeeGang Wu

Sustainable synthesis of Ammonia (NH3) is gaining great attention not only for its use as an alternative renewable energy fuel but also to substitute production of distributed fertilizers through the conventional Haber Bosch process. The conventional Haber-Bosch process to produce NH3 uses fossil fuels in deriving hydrogen from steam reforming of natural gas, is energy intensive and also leads to significant CO2 emission. Alternatively, electrochemical synthesis of ammonia (ESA) through the nitrogen reduction reaction (NRR) in alkaline medium saves the use of hydrogen as a reactant as the aqueous electrolyte forms the source of proton. However, the standard reduction potential…
