Kinetic and deuterium isotope analyses of ammonia electrochemical synthesis.

ABSTRACT: The mechanism of electrochemical promotion of ammonia formation was investigated by kinetic and deuterium isotope analyses using a cell with a Pt (anode)|BaCe_0.9Y_0.1O₃ (BCY)|Fe (cathode) configuration on the introduction of a gaseous mixture of H₂(D₂)-N₂ to the cathode at 550 °C. To clarify the mechanism of electrochemical ammonia synthesis, the reaction orders for hydrogen, α, and nitrogen, β, were investigated. The values of α and β did not change after applying a negative voltage, which indicates that the reaction mechanism at rest potential is the same as that with cathodic polarization. Furthermore, deuterium isotope analysis was conducted to investigate the mechanism of electrochemical promo
