In article number 1903693, Jin Goo Lee, John T. S. Irvine and co‐workers develop a highly efficient, solvothermal route to exsolution from smaller scale primary particles. Unlike previous reports, it seems that the metal nanoparticles are exsolved from the A‐site of these perovskites. The catalysts show large active site areas and strong metal‐support interaction, leading to higher activity and stability for the oxygen‐evolution reaction.
