• Demonstrate that the key factor to determine the activity of reconstructed surfaces is the surface chemistry, instead of reconstruction degree using the popular perovskite LaNi_1-xFe_xO₃ oxides as model materials.

• Fe content can influence both the surface reconstruction degree, the activation degree, and the activity of reconstructed surfaces.

• The oxygen evolution reaction activity of reconstructed catalysts is primarily governed by the chemistry of the reconstructed surface species.
