N‐doped carbon nanocages (NCNCs) with large specific surface area up to 1393 m 2 g −1 are produced for the first time, which demonstrate excellent ORR performances with high activity. Without the interference of any ORR‐active metal impurities in NCNCs, the experimental results confirm the origin of ORR activity from the N‐doped carbon species. Further details can be found in the article by Zheng Hu, Xizhang Wang, and co‐workers on page 5593 .
