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　(O-2)　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　O-2,　facilitating　the　production　of　critical　superoxide　radical　via　the　O-2　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　O-2　activation.
