Amine-impregnated　adsorbents　have　promising　application　for　selective　CO　2　capture　from　dilute　sources　in　the　industry.　It　is　of　great　significance　to　develop　a　support　exhibiting　not　only　large　pore　width　but　also　high　pore　volume,　that　can　be　prepared　from　renewable　and　low-cost　raw　materials.　In　this　work,　a　mesoporous　carbon　exhibiting　the　total　pore　volume　of　3.04　cm　3　/g　was　prepared　from　chitosan　by　a　hard-template　route.　The　mesoporous　carbon　was　then　physically　impregnated　with　pentaethylenehexamine,　which　is　rich　in　amine　density　and　of　extremely　low　volatility.　It　is　demonstrated　that　the　adsorption　capacities　for　CO　2　and　selectivities　for　CO　2　/N　2　on　mesoporous　carbon　are　significantly　improved　after　the　amine　impregnation.　The　highest　CO　2　uptake　of　3.72　mmol/g　at　100　°C　under　atmospheric　pressure　was　achieved　in　amine-impregnated　carbons,　being　higher　than　most　of　other　amine-impregnated　adsorbents　that　have　ever　been　reported　in　the　literature.　Furthermore,　the　CO　2　adsorbed　by　amine-impregnated　carbon　can　be　facilely　stripped　out　by　concentration　swing　at　75　°C,　and　the　amine-impregnated　carbon　exhibit　high　stability　throughout　consecutive　adsorption-desorption　cycles.　©　2018　Elsevier　B.V.
