Mechanistic Insights into the Stabilization of In Situ Formed γ‐NiOOH Species on Ni60Nb40 Nanoglass for Effective Urea Electro‐Oxidation

The formation of NiOOH on the catalyst surface is widely considered to be the active species in electrochemical urea oxidation reactions (UOR). Though in situ-formed NiOOH species are reported to be more active than the synthesized ones, the mechanistic study of the actual active species remains a daunting task due to the possibility of different phases and instability of surface-formed NiOOH. Herein, mechanistic UOR aspects of electrochemically activated metallic Ni
