The Cover Feature shows the potential‐driven phase transformation of Manganosite (Mn II O) to layered Birnessite (Mn III,IV O 2 ) in alkaline media. In their Full Paper, H. Radinger et al. investigate the structural and chemical evolution of various MnO x thin films as electrocatalysts for the oxygen evolution reaction by X‐Ray photoelectron and operando Raman spectroscopy. The displayed conversion with intercalated water molecules and potassium ions is responsible for the electrochemical performance. Nevertheless, the starting material defines the electrocatalytic activity after an electrochemical activation treatment. More information can be found in the Full Paper by H. Radinger et al.
