Improvements in the evaluation of electrocatalytic ammonia oxidation reactions

For a reliable evaluation of the electrocatalytic ammonia oxidation reaction (EAOR), we revised the standard electrode potentials in both aqueous and nonaqueous electrolytes using the solvation energies of ammonia. Moreover, we developed an improved assessment protocol for EAOR systems, particularly for those employing nonaqueous electrolytes and/or nitrogen-containing materials. The revised standard electrode potentials and improved protocol will accelerate the R&D of high-performance catalysts and electrolytes for electrocatalytic ammonia oxidation reactions.
