Selective　catalytic　oxidation　of　H2S　into　elemental　sulfur　has　been　recognized　as　the　optimal　route　for　H2S　reutilization,　but　traditional　metal　catalysts　show　poor　sulfur　resistance.　Herein,　we　report　a　solvent-free　route　for　designing　nitrogen　and　defects　co-doped,　ordered　mesoporous　carbons　(ND-OMCs)　from　co-assembly　of　block　copolymer　template　with　nitrogen-containing　oligomers　and　silica　defects　directing　agent.　Through　thermal　curing,　carbonization　and　etching　of　silica,　the　microporosity　tandem　ordered　mesopores,　abundant　nitrogen　sites　(6.13　wt%)　and　structural　defects　were　introduced　into　ND-OMCs.　The　ND-OMCs　were　successfully　applied　as　efficient　and　long-lived　metal-free　catalysts　for　H2S　selective　oxidation　to　sulfur,　giving　nearly　100　%　H2S　conversion　and　sulfur　selectivity　at　only　150　°C.　Their　remarkable　activities　of　ND-OMCs　can　be　well-maintained　over　157　h　of　continuous　reaction,　exhibiting　the　sulfur　capacity　as　high　as　3295　mg/g,　which　were　much　better　than　mostly　desulfurizes　such　as　commercial　Fe2O3,　g-C3N4,　and　nitrogen-containing,　ordered　mesoporous　carbons.　©　2023　Elsevier　Ltd
