Presented　here　are　the　synthesis　of　series　N-rich　hierarchically　porous　carbons　via　disposition　of　ZIF-8　on　g-C　3　N　4　nanosheets　and　their　uses　as　electrode　materials　in　oxygen　reduction　reaction　(ORR)　and　supercapacitor.　Electron　microscopy　images　show　the　successful　formation　of　2D　carbon　structures　through　using　layered　C　3　N　4　as　a　novel　template　and　ZIF-8　as　carbon　precursor.　The　meso　and　macropores　of　the　ZIF-8　derived　carbons　are　significantly　developed　with　g-C　3　N　4　incorporation.　Electrochemical　measurements　demonstrate　that　the　resulting　2D　carbons　exhibit　enhancing　performance　of　supercapacitance　up　to　159.0　F/g　at　a　current　density　of　1　A/g,　meanwhile　the　optimized　electrocatalytic　activity　for　ORR　in　O　2　saturated　0.1　M　KOH　electrolyte,　with　a　distinct　oxygen　reduction　peak　at　0.71　V　that　was　comparable　to　the　value　of　the　referenced　Pt/C　catalyst.　Notably,　this　is　the　first　investigation　of　layered　g-C　3　N　4　supported　ZIF-8　derived　carbons　for　ORR　and　supercapacitance.　This　work　may　offer　a　new　way　to　prepare　novel　electrocatalysts　by　effective　integration　of　ZIF-8　derived　carbon　and　the　g-C　3　N　4　skeleton.　©　2018　Wiley-VCH　Verlag　GmbH　&　Co.　KGaA,　Weinheim
