Bi2WxMo1_xO6/BiOBr　composites　was　prepared　by　a　one-pot　hydrothermal　method　from　the　W-Mo　alloy　scrap　as　the　raw　material,　and　commercially　available　scientific　reagents　were　used　as　raw　materials　to　simulate　different　secondary　resources.　The　products　have　a　hydrangea-like　structure,　forming　an　orthorhombic　crystal　structure.　Adjusting　the　W/Mo　molar　ratio　(M(W):M(Mo))　of　Bi2WxMo1_xO6/BiOBr　was　adjusted　as　0:1,　1:3,　1:2.17,　1:2,　1:1,　3:1,　and　1:0,　and　the　results　show　that　the　Bi2W0.5Mo0.5O6/BiOBr　composites　prepared　at　M(W):M(Mo)　=　1:1　has　the　best　photocatalytic　degradation　performance　for　tetracycline　(TC),　with　a　removal　rate　of　93.33　%　within　180　min　and　the　removal　rate　remains　at　85　%　after　four　degradation　cycles.　The　Bi2W0.5Mo0.5O6/BiOBr　composites　forms　a　type　II　heterojunction,　which　accelerates　the　separation　of　electrons　(e_　)　and　hole　(h+),　thereby　enhancing　the　photocatalytic　performance.　This　study　show　that　it　is　feasible　to　prepare　Bi2WxMo1_xO6/BiOBr　composites　from　W-Mo　alloy　scrap.　The　process　is　simple　and　effective,　providing　a　potential　approach　for　the　recycling　and　utilization　of　secondary　resources.
