Effective　advancements　for　H2S　removal　are　desperately　expected　to　meet　security　and　ecological　necessities　as　natural　guidelines　on　H2S　emissions.　Selective　catalytic　oxidation,　as　a　green　technology,　has　attracted　attention　owing　to　its　direct　conversion　of　H2S　to　S　without　thermodynamic　constraints.　Herein,　we　report　a　carbon-encapsulated　WO3　(C@WO3–300)　catalyst　with　nearly　100　%　H2S　conversion　and　99　%　S　selectivity.　Importantly,　it　likewise　accomplishes　noteworthy　catalytic　stability　(over　120　h　of　continuous　operation)　and　water　resistance.　Excellent　durability　may　be　attributed　to　the　ideal　porosity　of　C@WO3,　which　facilitates　the　adsorption　and　activation　of　H2S　and　O2.　Additionally,　the　abundant　lone　pair　electrons　of　carbon　support　can　optimize　the　chemical　environment　of　WO3-based　catalysts　and　thereby　benefit　the　O2　activation.　This　study　provides　a　new　avenue　for　the　rational　design　of　efficient　and　durable　catalysts　for　continuous　catalytic　oxidative　desulfurization.　©　2024
