AB  - The development of new technologies for efficient degradation of pollutant has 
      been an increasing demand in the globe due to the serious environmental issues. 
      Herein, we report n-type ZnO/p-type BiFeO(3) composites as highly efficient 
      visible light nanophotocatalysts prepared via a wet chemical solution method. 
      Based on the measurements of (*)OH-related fluorescence (FL) spectra, 
      photoluminescence (PL) spectra, photoelectrochemical I-V curves, and 
      electrochemical impedance spectra (EIS), it is demonstrated that the 
      photo-induced charge carrier (electron-hole pairs) in the as-prepared n-type 
      ZnO/p-type BiFeO(3) composites with proper amount of the coupled ZnO (10% by 
      mass) exhibits high separation compared with the bare BiFeO(3) (BFO) 
      nanoparticles. This is well responsible for the superior visible light 
      photocatalytic performance of the composites for 2,4-dichlorophenol (2,4-DCP) and 
      rhodamine B (RhB) degradation. It is confirmed by means of scavenger test and 
      liquid chromatography-tandem mass spectrometry (LC/MS) analysis of the 
      intermediate products that (*)OH is the pre-dominant oxidant involved in the 
      degradation of 2,4-DCP. A detailed reaction pathway for 2,4-dichlorophenol 
      degradation over the amount-optimized ZnO/BFO composite is proposed mainly based 
      on the LC/MS product ions. This work will provide a feasible route to design and 
      develop BFO-based highly efficient visible light-active photocatalysts for 
      environmental purification and could be extended to other visible light-active 
      semiconductor materials.
