electrochemical ammonia production via the associative mechanism is possible at potentials as low as −0.45 V to −0.7 V.

Molybdenum nanoclusters have been identified as a prime candidate for
rise to oxygen or hydroxide adsorption on the surface, which can occupy or block important surfaces sites. The adsorbed oxygen species can either decrease or totally hinder other chemical reactions taking place at that site. Oxygenpoisoning of the surface is indeed a main inhibitor for ammonia
