英文摘要	Hierarchical graphitic porous carbon architectures with atomically dispersed fe and n doping have been fabricated from a metal organic framework (mof) composite by using a facile strategy, which show high specific surface areas, hierarchical pore structures with macro/meso/micro multimodal pore size distributions, abundant surface functionality with single-atom dispersed n and fe doping, and improved hydrophilicity. detailed analyses unambiguously disclosed the main active sites of doped n atoms and fenx species in the catalyst. the resultant catalyst affords high catalytic performance for oxygen reduction, outperforming the benchmark pt catalyst and many state-of-the-art noble-metal-free catalysts in alkaline media, particularly in terms of the onset and half-wave potentials and durability. such catalytic performance demonstrates the significant advantages of the unique hierarchical porous structure with efficient atomic doping, which provides a high density of accessible active sites for much improved mass and charge transports.
