A silica‐mediated MOF‐templated (SMMT) approach is used to generate an overhang‐eave carbon cage decorated with single‐atom iron catalysts for oxygen reduction (ORR), as reported by Q. Xu and co‐workers in their Communication (DOI: 10.1002/anie.202002665). This structure furnishes more stretched edges as compared to three‐phase boundaries, supporting the mass transport of ORR‐relevant species and providing maximum exposure of the atomically dispersed/catalytically active iron sites, thus increasing the utilization of each active sites.
