A　simple　hydrothermal　method　was　used　to　synthesize　W-Mo　bimetallic　sulfides　(Mo1-xWxS2)　from　W-Mo　alloy　scrap,　and　a　series　of　Mo　1-x　W　x　S　2　nanoflower　with　different　tungsten　molybdenum　ratios　were　prepared　by　simulating　the　leaching　solution　of　the　scrap.　The　products　are　three-dimensional,　flower-like　spherical　structure　assembled　by　interlacing　nanosheets,　exhibiting　two　crystal　phases:　1　T　and　2H.　High　piezoelectric　catalytic　activity　was　achieved　by　optimizing　the　crystal　structure　and　atomic　doping.　The　alloyed　Mo　1-x　W　x　S　2　nanoflowers　with　the　1　T　phase　concentration　of　48.2%　exhibits　the　highest　piezoelectric　catalytic　activity,　with　degradation　rates　of　93.96%,　60.52%,　and　65.67%　for　methylene　blue　(MB),　rhodamine　B　(RhB),　and　tetracycline　(TC),　respectively.　Additionally,　we　also　elaborated　on　the　influence　of　N,　N-Dimethylformamide　(DMF)　on　the　morphology　and　crystal　phase.　The　results　indicate　that　the　flower-shaped　Mo　1-x　W　x　S　2　exhibits　a　strong　piezoelectric　response.　This　work　provides　a　novel　and　efficient　approach　for　resource　recycling,　wastewater　treatment　and　environmental　catalytic　applications.
