Hydrogen　sulfide　(H2S)　is　a　notorious　andlethal　gaswidely　generated　in　human　economic　activities　and　natural　occurrences.The　growing　demand　for　pollution　control　makes　it　vital　for　the　developmentof　efficient　processes　to　remove　and　convert　H2S　into　high-valuedproducts.　As　such,　diversified　technologies　have　been　extensivelyexplored,　including　H2S　splitting,　selective　oxidationof　H2S,　and　simultaneous　conversion　of　H2S　andCO(2).　In　this　review,　the　state-of-the-art　processes　forH(2)S　conversion　and　utilization　are　reviewed.　The　potentialsof　various　value-added　products　from　H2S　utilization,　suchas　H-2,　syngas,　COS,　CH3SH,　and　other　sulfur-containingfine　chemicals　are　elucidated　in　detail.　Notably,　the　traditionaland　emerging　materials　for　H2S　removal,　mainly　includingmetal　oxide　catalysts　and　carbon-based　materials　are　also　overviewedin　this　review.　In　addition,　the　catalytic　mechanisms　for　these　desulfurizationreactions　are　also　briefly　discussed.　Lastly,　perspectives　are　givenon　the　viability　and　technological　gaps　for　each　technology　and　correspondingcatalysts.
