  "abstract": "Ammonia has recently attracted significant attention as a green fuel for fuel cells due to its advantages over hydrogen.Electrochemical ammonia oxidation has traditionally relied on noble metal catalysts such as Pt.However, scarcity and poisoning issues have motivated the exploration of molecular complexes as alternatives.Herein, we report iron tetraphenylporphyrin, Fe(TPP)Cl, as catalyst for electrochemical ammonia oxidation reaction (eAOR), both in homogeneous conditions, in dichloromethane (DCM) solutions, and incorporated in carbon black, in acetonitrile (ACN) solutions.Catalytic activity in homogeneous conditions is demonstrated by cyclic voltammetry whereas surface incorporation of the catalyst into catalytic films is confirmed by resonance Raman spectroscopy and cyclic voltammetry.It is a rare example of a non-noble metal, hybrid molecular catalysis for ammonia oxidation reaction.",
