Cover Feature: Comprehensive Structural Descriptor for Electrocatalytic Oxygen Evolution Activities of Iron Oxides (ChemElectroChem 23/2021)

The Cover Feature illustrates the unveiled structural descriptor for electrocatalysis on Fe-based oxides. Shorter Fe−O bond length is more beneficial for the electrocatalytic oxygen evolution reaction. The descriptor is applicable to a wide range of Fe-based multimetal oxides regardless of chemical compositions. More information can be found in the Article by Y. Sugawara et al.
