Local tensile strain boosts the electrocatalytic ammonia oxidation reaction

The introduction of local tensile strain in Ni(OH)2 nanosheets accelerates the Ni(OH)2-to-NiOOH transition and boosts the electrocatalytic ammonia oxidation reaction (EAOR), i.e., reducing the onset potential by 80 mV, doubling both the current density and N2 faradaic efficiency, and enabling 1000 hours of operation at 160 mA cm-2. Local tensile strain induces a 100 mV drop of the Ni(OH)2-to-NiOOH transfer potential, remarkably enhancing the electrocatalytic ammonia oxidation reaction.
