N2 - Energy generation from a sustainable renewable source is seen as an imperative tool to meet the energy demand of the present day. Moreover, obtaining clean energy fuel e.g., H2 is the need of the hour and hence, oxidation of ammonia might be a solution to this milestone. Mn2(CO3)3 deposited electrochemically on the surface of a Pd electrode is a good electrocatalyst for the oxidation of ammonia (AOR) to dinitrogen. The AOR occurs in solutions containing Na2CO3 and NH4OH as electrolytes. The Mn2(CO3)3/Pd electrode in 0.5 M NH4OH & 1.0 M Na2CO3 has a high electrocatalytic oxidation current density of 6.4 mA cm−2 at anodic potential of 1.16 V vs. NHE. Chronoamperometric experiments, for the durability test, point out that Mn2(CO3)3 is stable for over 4 h towards the ammonia oxidation reaction. Also, on careful investigation of the products formed upon oxidation of ammonia, only nitrogen as a product was observed.
