Aerobic　photocatalytic　oxidation　is　considered　as　an　efficient　and　green　method　to　remedy　low-concentration　H2S　pollutants　associated　with　the　energy　and　chemical　industries.　However,　the　fabrication　of　a　sulfur-resistant　catalyst　with　good　performance　is　a　great　challenge　because　of　the　poisoning　effect　of　H2S　and　the　difficulty　in　oxygen　(O2)　activation.　Herein,　a　photocatalytic　hybrid　material　composed　of　chemically　stable　cobalt　phosphide　(CoP)　and　structural　base-enriched　carbon　nitride　(CN)　was　developed　for　the　efficient　oxidation　of　H2S,　which　could　achieve　95%　H2S　conversion,　and　its　service　time　could　last　more　than　35　h　with　over　80%　H2S　conversion.　Reflecting　from　the　characterizations　and　theoretical　simulations,　the　enhanced　H2S　conversion　was　on　account　that　CoP　could　stimulate　the　electrons　shuttling　from　the　photocatalytic　system　towards　the　gaseous　O2,　facilitating　the　production　of　critical　superoxide　radical　via　the　O2　reduction　process　and　accelerating　the　surface　H2S　oxidation　process.　This　work　provides　new　insights　into　the　design　of　a　sustainable　photocatalytic　oxidation　system　for　the　treatment　of　chemically　active　contaminants　through　constructing　stable　interfacial　electron　transfer　channels　for　prominent　O2　activation.　©　2024　The　Royal　Society　of　Chemistry.
