As　a　highly　toxic　and　corrosive　waste　gas　in　the　industry,　hydrogen　sulfide　(H2S)　usually　originates　from　the　utilization　of　coal,　petroleum,　and　natural　gas.　The　selective　catalytic　elimination　of　H2S　shows　great　significance　to　ensure　the　safety　of　industrial　processes　and　health　of　human　beings.　Herein,　we　report　efficiently　selective　oxidation　of　H2S　to　elemental　sulfur　over　covalent　triazine　framework　(CTF-1-x,　x　=　400,　500,　600,　400-600　°C)　catalysts.　CTF-1-x　samples　were　prepared　from　polymerization　of　1,4-dicyanobenzene　to　form　polyaryl　triazine　networks　under　ion　solidothermal　conditions　in　the　presence　of　ZnCl2,　which　acts　as　both　an　initiator　and　a　porogen.　The　resultant　CTF-1-x　samples　possess　abundant　micro-mesoporosity,　large　Brunauer-Emmett-Teller　(BET)　surface　areas,　and　tunable　structural　base　sites　with　edge　amine　and　graphitic　nitrogen　characteristics,　which　were　homogeneously　decorated　onto　their　frameworks.　As　a　result,　CTF-1-x　samples　act　as　efficient　and　long-lived　catalysts　in　selective　oxidation　of　H2S　to　sulfur　under　ambient　conditions　(100%　H2S　conversion,　100%　sulfur　selectivity　at　180　°C,　12　000　mL/(g·h)),　and　their　activities　were　superior　to　those　of　commercial　Fe2O3　and　g-C3N4　desulfurization　catalysts.　Abundant　nitrogen　structural　base　sites　of　CTF-1-x　effectively　activate　the　reactants,　and　abundant　micro-mesoporosity　facilitates　mass　transfer　in　and　out　of　CTF-1-x.　The　improved　design　of　the　nitrogen-doped　carbon　material　for　H2S　activation　and　conversion　could　enhance　the　development　of　more　active　and　robust　nitrogen-doped　carbon　catalysts.　©　XXXX　American　Chemical　Society.
