Front Cover: Crystal Structures of Iron‐Based Oxides and Their Catalytic Efficiencies for the Oxygen Evolution Reaction: A Trend in Alkaline Media (ChemElectroChem 9/2022)

The Front Cover illustrates that artificial intelligence facilitates the understanding of science in electrocatalysis on heterogeneous crystalline compounds. Machine learning method demonstrates that alkaline oxygen evolution reaction on iron‐based multimetal oxides is uniquely controlled by a structural descriptor, Fe–O bond length, and the trend is generally applicable regardless of chemical compositions, valence states of iron and structural categories of the crystals.
