Tuning the electrocatalytic nitric oxide reduction activity of copper through alloying with nickel for NH3 production at low overpotentials

The electrocatalytic activity of Cu is significantly improved by alloying with Ni for reduction of NO to NH 3 . A high FE NH 3 of about 79% is attained from Cu 75 Ni 25 @NC at an overpotential of 610 mV (0.1 V vs. RHE).
