Developing　highly　efficient　catalysts　for　the　transformation　of　hydrogen　sulfide　(H2S)　pollutants　into　value-added　products　is　crucial　for　both　fundamental　catalytic　research　and　industrial　chemistry.　Herein,　ferrititanate　nanosheets　(H0.8Ti1.2Fe0.8O4,　denoted　as　NS-HTFO)　exfoliated　from　lepidocrocite-type　titanates　are　employed　for　the　first　time　to　catalyze　the　conversion　of　H2S　to　elemental　sulfur.　Collective　experimental　characterizations　reveal　that　the　as-designed　NS-HTFO　catalyst　possesses　ultrathin　2D　structure　and　a　large　specific　surface　area,　featuring　abundant　oxygen　vacancies.　Compared　with　its　sandwich-like　precursor　of　K0.8Ti1.2Fe0.8O4　(denoted　as　L-KTFO),　the　NS-HTFO　catalyst　displays　notably　enhanced　desulfurization　activity,　achieving　100　%　H2S　conversion　and　over　93　%　sulfur　selectivity　at　temperatures　ranging　from　90　to　270　°C.　Moreover,　no　significant　decline　in　sulfur　yield　is　observed　over　the　course　of　a　100-hour　evaluation,　showing　outstanding　breakthrough　sulfur　capacity　up　to　4163　mg/gcat.　This　performance　exceeds　that　of　most　recently　reported　catalysts.　The　possible　catalytic　mechanism　for　H2S-to-S　selective　oxidation　over　the　NS-HTFO　catalyst　has　also　been　investigated.　©　2024　Elsevier　B.V.
