摘要：

Metal-free ORR Electrocatalysts: N-doped carbon nanocages (NCNCs) with large specific surface areas of up to 1393 m(2) g(-1), which demonstrate excellent ORR performance with high activity, are produced for the first time. Without the interference of any ORR-active metal impurities in NCNCs, the experimental results confirm that the ORR activity originates from the N-doped carbon species.
