Heteroatom　doped　porous　carbon　materials　have　great　application　prospects　in　supercapacitors.　In　the　present　study,　an　approach　of　preparing　N-doped　porous　carbon　(NPC)　was　proposed　from　porous　poly(resorcinolformaldehyde-melamine)　monoliths　which　were　prepared　by　high　internal　phase　emulsion　(HIPE)　template.　Melamine　was　dissolved　in　the　external　phase　and　copolymerized,　acting　as　the　N　source　and　porous　structure　regulator　to　provide　micropore-dominant　NPCs.　The　structure,　morphology,　specific　surface　area　(SSA),　and　chemical　composition　of　the　samples　were　systematically　studied.　With　melamine　content　increasing,　N-doping　content　in　NPC　increased　while　the　SSA　of　NPC　increased　at　first　and　then　decreased.　When　the　content　of　N　is　8.42　wt%,　the　obtained　NPC　showed　the　highest　SSA　of　about　1670　m2　g-1.　Furthermore,　high　N　doping　content　could　improve　the　electronic　conductivity　and　provide　additional　pseudocapacitance　of　NPC.　Under　the　combined　influences　of　proper　N　content　and　high　porosity,　the　prepared　NPC　electrodes　revealed　excellent　specific　capacitance　(228.0　F　g-1　at　1.0　A　g-1),　favorable　circling　stability,　and　prominent　rate　capability　in　a　threeelectrode　system　with　6　M　KOH　solution　as　the　electrolyte.
