Outline of Final Research Achievements

In this study, we used MOFs as templates/precursors to prepare hierarchically porous carbon materials for energy storage and conversion. Hierarchically porous carbons with both micro- and mesopores synthesized by direct carbonization of assembled nanoparticles of ZIF-8 have been used as supports for highly active Pd electrocatalysts for methanol electrooxidation. Hierarchical graphitic porous carbon architectures with atomically dispersed Fe and N doping have been fabricated from a 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 reaction.
