Metal　sulfides　have　been　found　to　be　effective　in　removing　organic　pollutants　from　water　in　environmental　catalysis.　In　this　study,　a　porous　graphitic　biochar　wrapped　Co9S8　core-shell　composite　(Co9S8@N-O-BC)　was　designed　for　efficient　activation　of　peroxymonosulfate　(PMS)　and　degradation　of　sulfamethoxazole　in　an　aqueous　environment.　Based　on　complementary　characterizations　and　reactive　oxygen　species　(ROS)　quenching　experiments,　we　proposed　that　boosted　Co(ii)　regeneration　by　various　existing　S　species　along　with　formed　N　and　O　active　sites　in　Co9S8@N-O-BC　facilitated　the　cleavage　of　the　O-O　bond　of　PMS,　thus　resulting　in　a　high-efficiency　non-radical　pathway.　Consequently,　Co9S8@N-O-BC/PMS　achieved　an　outstanding　degradation　of　sulfamethoxazole　(100%)　within　4　min　in　a　wide　pH　range　(3-11)　and　its　turnover　frequency　(TOF)　value　was　11.96　min(-1),　up　to　117　times　higher　than　other　reported　catalysts　as　far　as　we　know.　The　superior　stability　and　wide　applicability　in　sulfamethoxazole　degradation　with　a　series　of　inorganic　ions,　especially　the　production　of　very　few　harmless　intermediates　and　the　exceptional　mineralization　efficiency,　also　further　demonstrated　that　the　obtained　catalyst　possessed　excellent　potential　for　practical　wastewater　treatment.
