Facile　preparation　of　N-doped　hierarchically　porous　carbons　(NHPCs)　is　an　important　research　direction　in　highperformance　supercapacitors　(SCs).　In　this　paper,　we　report　a　high　internal　phase　emulsion　(HIPE)　template　method　to　prepare　NHPCs　from　melamine　resins　with　the　aid　of　sucrose　or　glucose,　referred　as　S-NHPCs　or　GNHPCs,　respectively.　Sucrose　or　glucose,　formaldehyde,　and　melamine　are　dissolved　in　water　as　the　continuous　phase　of　the　HIPE.　Under　acid　catalysis,　the　continuous　phase　is　cross-linked　through　aldimine　condensation　to　produce　porous　melamine　resins.　Meanwhile,　carbohydrate　is　incorporated　via　the　interaction　between　the　rich　oxygen-containing　functional　groups　(-OH,　-C--OH)　of　carbohydrate　and　the　-NH2　groups　of　melamine　through　hydrogen　bonding　and　acetal　reaction.　After　carbonization　and　activation,　S-NHPCs　or　G-NHPCs　with　high　specific　surface　areas　(SSA)　are　obtained　respectively.　Besides　regulating　the　porous　morphology,　biomass　carbohydrate　can　enhance　the　electrochemical　properties　of　NHPCs　via　increasing　the　SSA　and　hydrophilicity　of　NHPCs.　The　SSA　of　S-NHPC　and　G-NHPC　increased　notably　from　823　to　1682　m2　g-1　and　1913　m2　g-1,　respectively.　Meanwhile,　owing　to　the　comprehensive　N-doping　and　the　developed　porous　structure,　the　prepared　NHPC　based　electrodes　exhibit　excellent　specific　capacitances　(up　to　305　F　g-1　at　1　A　g-1),　satisfactory　cycling　stability,　and　remarkable　rate　performance　in　a　three-electrode　system.
