Abstract：

Construction　of　metal-free　carbon-based　materials　for　efficient　sulfur　resource　recovery　in　pollutant　H2S　is　very　critical　for　both　applied　environmental　catalysis　and　fundamental　material　exploration.　Herein,　we　report　a　template-free　hydrothermal　method　to　prepare　hierarchical　nitrogen-doped　mesoporous　carbon　(HNMCs)　materials　with　abundant　nitrogen　sites　and　large　BET　surface　area.　The　representative　HNMC-800　achieves　a　H2S　conversion　of　∼100%　and　sulfur　selectivity　of　∼95%　at　150　°C　in　H2S　selective　oxidation.　Moreover,　HNMCs　catalysts　are　resistant　to　sulfur　poisoning,　displaying　good　catalytic　durability,　with　no　significant　loss　of　sulfur　yield　in　the　run　of　80　h,　outperforming　the　pure　active　carbon,　g-C3N4,　and　commercial　Fe2O3.　This　work　provides　the　possibility　of　utilizing　hierarchical　nitrogen-doped　carbon　materials　as　metal-free　catalysts　for　the　selective　oxidation　of　H2S.　©　2022　Elsevier　Ltd.
