Electrochemical and chemical instability of vanadium nitride in the synthesis of ammonia directly from nitrogen
ChemCatChem, 2020•Wiley Online Library
Recently, vanadium nitride (VN) was proposed as an active catalyst for a challenging
electrochemical nitrogen reduction reaction (NRR) to ammonia. In this study, the stability of
vanadium‐nitride in electrolyte solutions of different pH values was studied under selected
cathodic potentials. Intensive leaching of vanadium ions and nitrogen constituents into the
bulk of the electrolyte solution was confirmed from ICP‐OES and UV‐Vis results.
