Efficient Electrocatalytic Synthesis of Ammonia from Water and Air in a Membrane-free Cell: Confining the Iron-oxide Catalyst to the CathodeAmmoniaElectrochemical synthesisIronAmmonia is critical for food and chemical production; however, NH3 synthesis is one of the largest industrial greenhouse ...
The electrocatalytic nitrogen reduction reaction (NRR) is a sustainable and environmentally friendly strategy for the synthesis of ammonia. Although lots of electrocatalysts have been developed for this reaction, further breakthroughs are needed in catalytic activity, selectivity and Faraday efficiency to ...
Density functional theory calculations indicate that the electron-deficient sites show a much lower energy barrier (0.76 eV) for the potential determining step compared with that of the pristine NiFe-LDH (2.02 eV). Benefiting from this, the NiFe-LDH with oxygen vacancies exhibits the greatly ...
