Local tensile strain boosts the electrocatalytic ammonia oxidation reaction

Abstract

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.
