Being　abundant　and　active,　Fe2O3　is　suitable　for　selective　oxidation　of　H2S.　However,　its　practical　application　is　limited　due　to　the　poor　sulfur　selectivity　and　rapid　deactivation.　Herein,　we　report　a　facile　template-free　hydrothermal　method　to　fabricate　porous　alpha-Fe2O3/SnO2　composites　with　hierarchical　nanoflower　that　can　obviously　improve　the　catalytic　performance　of　Fe2O3.　It　was　disclosed　that　the　synergistic　effect　between　alpha-Fe2O3　and　SnO2　promotes　the　physico-chemical　properties　of　alpha-Fe2O3/SnO2　composites.　Specifically,　the　electron　transfer　between　the　Fe2+/Fe3+　and　Sn2+/Sn4+　redox　couples　enhances　the　reducibility　of　alpha-Fe2O3/SnO2　composites.　The　number　of　oxygen　vacancies　is　improved　when　the　Fe　cations　incorporate　into　SnO2　structure,　which　facilitates　the　adsorption　and　activation　of　oxygen　species.　Additionally,　the　porous　structure　improves　the　accessibility　of　H2S　to　active　sites.　Among　the　composites,　Fe1Sn1　exhibits　complete　H2S　conversion　with　100%　sulfur　selectivity　at　220　degrees　C,　better　than　those　of　pure　alpha-Fe2O3　and　SnO2.　Moreover,　Fe1Sn1　catalyst　shows　high　stability　and　water　resistance.　(C)　2021　Chinese　Chemical　Society　and　Institute　of　Materia　Medica,　Chinese　Academy　of　Medical　Sciences.　Published　by　Elsevier　B.V.　All　rights　reserved.
