Developing　a　suitable　catalyst　for　the　elimination　of　highly　toxic　carbonyl　sulfide　(COS)　and　hydrogen　sulfide　(H2S)　is　of　great　significance　in　terms　of　industrial　safety　and　environmental　protection.　We　demonstrate　here　the　facile　synthesis　of　graphitized　2D　micro-meso-macroporous　carbons　by　one-step　carbonization　of　a　mixture　of　urea　and　glucose　at　700-900　degrees　C.　The　as-synthesized　graphitized　catalysts,　designated　as　2DNHPC-x　(x　=　urea/glucose　mass　ratio),　are　endowed　with　an　ultra-high　concentration　(12.9-20.2　wt%)　of　stable　and　versatile　nitrogen　sites　(e.g.　pyrrole　and　pyridine)　which　are　anchored　on　the　surface　via　stable　covalent　bonding.　As　a　result,　the　2D-NHPC-x　are　active　in　catalytic　hydrolysis　of　COS　on　pyrrolic　N　to　H2S,　and　the　H2S　can　be　subsequently　captured　on　pyridinic　N　and　converted　to　elemental　sulfur　at　ambient　conditions　over　the　same　materials.　Among　the　prepared　catalysts,　2D-NHPC-x　can　catalytically　hydrolysize　91%　of　COS　to　H2S　at　30　degrees　C,　whereas　the　conversion　ratio　over　the　common　catalysts　g-C3N4　and　Fe2O3　are　below　6.0%.　Furthermore,　these　catalysts　also　exhibit　H2S　conversion　and　sulfur　selectivity　of　nearly　100%　at　180　degrees　C　with　long-time　durability,　which　is　higher　than　those　of　the　most　reported　carbonbased　catalysts.　In　contrast,　the　H2S　capacities　of　activated　carbon,　ordered　mesoporous　carbons　(OMC)　and　N-doped　OMC　are　3.9,　1.5　and　2.39　mmol　g-1,　respectively.　Both　the　experimental　and　theoretical　results　are　disclosed　that　2D-NHPC-x　are　superior　to　the　nitrogen-doped　porous　materials　ever　applied　in　simultaneous　catalytic　elimination　of　both　COS　and　H2S.　(c)　2020　Institute　of　Process　Engineering,　Chinese　Academy　of　Sciences.　Publishing　services　by　Elsevier　B.V.　on　behalf　of　KeAi　Communications　Co.,　Ltd.　This　is　an　open　access　article　under　the　CC　BY-NC-ND　license　(http://creativecommons.org/licenses/by-nc-nd/4.0/).
