Electrocatalytic Oxidation of Ammonia by (Salen)ruthenium(III) Ammine Complexes: Direct Evidence for a Ruthenium(VI) Nitrido Active Intermediate.

ABSTRACT: The electrocatalytic oxidation of ammonia using molecular catalysts has attracted much attention recently due to its potential for fuel cell applications. In this study, we report the electrocatalytic ammonia oxidation (AO) by [Ru^III(salchda)(NH₃)(CH₃CN)]⁺ (RuNH₃, salchda = N,N'-bis(salicylidene)-o-cyclohexyldiamine dianion) and its bromo derivative. Controlled potential electrolysis at 0.65 V versus Fc^+/0 for 3.2 h of a solution of RuNH₃ and NH₃ in CH₃CN produced N₂ with a TON of 26 and Faradaic efficiency (FE) close to 100%. The TON was increased to 79 and 147 when electrolysis was carried out at 0.7 and 0.80 V vs Fc^+/0, respec
