Electrocatalytic Ammonia Oxidation by a Ruthenium Complex Bearing a 2,6-Pyridinedicarboxylate Ligand.

ABSTRACT: Molecular catalysts for the electrocatalytic ammonia oxidation reaction (eAOR) have much to offer in terms of mechanistic investigations and practical energy issues. This work reports the use of complex [Ru(pdc-κ-N¹O²)(bpy)(NH₃)] (Ru-NH ₃ ) (H₂pdc = 2, 6-pyridinedicarboxylic acid; bpy = 2,2'-bipyridine) bearing a readily accessible pdc^2- ligand to catalyze ammonia oxidation under electrochemical conditions. The rich structural variations of Ru-NH ₃ in coordinating solvents and an ammonia atmosphere were fully characterized by cyclic voltammograms (CVs), NMR, and XRD. CV experiments showed that Ru-NH ₃ promotes electrocatalytic ammonia oxidation at a low overpote
