The　synergistic　piezo-photocatalysis　with　enhanced　efficiency　for　degrading　obstinate　pollutants　in　wastewater　is　considered　as　an　advanced　way　to　ameliorate　the　global　water　contamination.　In　this　work,　we　report　a　facile　route　to　construct　the　Bi0.5Na0.5TiO3@Ag　composite　by　photoreduction　of　AgNO3　to　obtain　Ag　on　Bi0.5Na0.5TiO3　nanoparticles.　And　the　composite　was　used　to　degrade　three　representative　pollutants,　i.e.　ciprofloxacin,　methyl　orange　and　mitoxantrone　hydrochloride.　Remarkably,　for　methyl　orange　solution　with　the　initial　concentration　of　10　mg/L,　the　degradation　rate　constant　of　the　composite　reached　0.051　min(-1).　H+　and　center　dot　O-2(-)　play　a　major　role　in　this　degradation　process,　verified　by　the　radical　quenching　experiments.　The　absorption　platform　of　Bi0.5Na0.5TiO3　was　located　in　the　UV　region,　after　introducing　Ag　in　the　composite,　the　absorption　region　broadened　to　both　UV　and　visible　light,　greatly　promoting　the　response　to　light.　Simultaneously,　the　induced　piezo-potential　by　mechanical　energy　in　Bi0.5Na0.5TiO3　hindered　the　carrier　recombination,　resulting　in　high　-efficiency　synergistic　piezo-photocatalytic　process.　This　work　provides　a　paradigm　to　innovate　both　material　and　catalytic　way　for　degrading　multiple　organic　pollutants.
