Photocatalytic　removal　of　tetracycline(TC)from　the　wastewater　is　of　great　value　in　the　chemical　and　environmental　engineering　field.Here,we　introduced　a　facile　one-step　method　for　the　synthesis　of　BiOBr/Bi2WO6　heterojunctions　by　using　cheap　CTAB　as　the　Br　source.We　showed　the　possibility　of　our　method　to　fine-tune　the　content　of　BiOBr　in　the　produced　BiOBr/Bi2WO6　by　simply　changing　the　dosage　of　cetyltrimethylammonium　bromide(CTAB),providing　a　platform　for　the　delicate　tuning　of　the　visible-light　absorbance　ability　of　the　composites.With　a　suitable　heterojunction　structure　of　BiOBr/Bi2WO6-0.2,it　exhibited　an　ultrarapid　photocatalytic　activity　towards　TC(20　mg·L-1),with　a　competitive　removal　effi-ciency　of　88.1％within　60　min　and　an　ultrahigh　removal　rate　of　0.0349　min-1.It　could　also　be　robustly　recycled　for　at　least　5　cycles　with　slight　removal　efficiency　loss.We　demonstrated　that　this　exciting　pho-tocatalytic　performance　was　due　to　the　highly　decreased　recombination　of　photoinduced　electrons　and　holes　on　our　composites　by　constructing　this　heterojunction　structure,and　the　resulting·OH　and·O2　con-tributed　to　the　effective　degradation　of　TC　to　CO2.
