From inert to active: a cocktail-like mediation of an Ag/Ni mixture for electrocatalytic ammonia oxidation reaction

We report a highly selective electrocatalytic ammonia oxidation reaction (EAOR) induced by handmilling inert powders of silver (NH3 adsorber) and nickel (OH- adsorber and active site). This cocktail-like mediation provides a good model for mechanistic understanding of the EAOR, benefiting the development of effective non-noble metal catalysts for the EAOR.
