(674c) Electrocatalyst Development for Making Ammonia from Air and Water at Ambient Condition

Renewable power generated from wave energy has faced technological and cost barriers that have hindered its penetration into utility-scale electricity markets. As an alternative, the production of chemical fuels—for example, ammonia (NH₃), which has a high energy density (11.5 MJ/L) and facile storage properties—may open wave energy to new markets including ocean exploration and transportation. We developed a unique catalyst and tested its performance toward nitrogen reduction reaction using the rotating round disk electrode (RRDE) method. The current density increased 0.25 mA/cm² after switching the gas from Ar to N₂ and the production rate of NH₃ and Faradaic efficiency (FE) are in the top list of reported results.
