Abstract：

In　this　work,　the　tuning　of　piezoelectric　and　energy-harvesting　are　realized　in　solvothermal　synthesized　Cl　doped　ZnO　nanorods　(NRs),　which　is　designed　to　boost　the　coupling　effect　of　piezo-photocatalysis　for　dye　decomposition.　For　the　optimal　sample　5%-Cl-ZnO,　the　coupling　constant　is　about　24.4　times　greater　than　that　of　pure　ZnO,　which　is　benefited　from　the　synergistic　effect　of　the　increased　radial　piezoelectric　properties　and　the　superiority　of　nanorods　structure.　Optimal　5%-Cl-ZnO　NRs　not　only　maintains　high　migration　efficiency　for　photo-generated　carriers　in　the　axial　direction,　but　also　separate　more　thoroughly　and　transmit　faster　in　the　radial　direction.　This　work　clearly　demonstrates　a　high　correlation　between　piezoelectricity　and　coupling　effect　of　piezo-photocatalysis,　and　provides　a　new　strategy　for　optimizing　the　transport　of　photogenerated　carriers　in　1D　photocatalyst.　©　2020　Elsevier　B.V.
