Manganese carbonate as an efficient electrocatalyst for the conversion of ammonia (NH4+/NH3) to dinitrogen

Electrochemical deposition of Mn 2 (CO 3 ) 3 on Pd electrode for the oxidation of ammonia (AOR). The Mn 2 (CO 3 ) 3 /Pd electrode in 0.5 M NH 4 OH & 1.0 M Na 2 CO 3 shows high current density of 6.4 mA cm −2 at 1.16 V vs. NHE. The catalyst shows stable activity >4 h.
