AB  - In this work, a Z-scheme BiFeO(3)-g-C(3)N(4)-WO(3) (BFO-CN-WO) photocatalyst has 
      been synthesized via a wet chemical method and utilized in photocatalysis for 
      hydrogen generation and 2,4-dichlorophenol (2,4-DCP) degradation under visible 
      light irradiation. The resultant photocatalyst showed 90 mumol.h(-1) g(-1) H(2) 
      evolution activity and 63% 2,4-DCP degradation performance, which is 12 and 4.2 
      times higher than the pristine g-C(3)N(4) respectively. The fascinating 
      photocatalytic performance is attributed to the strong interfacial contact 
      between g-C(3)N(4) and the coupled BiFeO(3) and WO(3) component, which greatly 
      improved the visible light absorption and charge carriers' separation. The 
      designed Z-scheme heterojunction is a successful strategy for enhancing the 
      separation efficiency of photo-induced charge carriers at the interface while 
      retaining outstanding redox ability. During 2,4-DCP degradation, LC/MS technique 
      was used to detect the reaction intermediates. According to the LC/MS results, 
      several new intermediates such as 2,3-dichloro-6-(2,4-dichlorophenoxy)phenol 
      (m/z = 306), 2,4-dichlorophenyl hydrogen carbonate (m/z = 207), 
      2,4-dichlorobenzen-1,3-diol (m/z = 177) and phenyl hydrogen carbonate (m/z = 137) 
      were detected. Based on these intermediates, 2,4-DCP degradation pathway is 
      proposed. The fluorescence (FL) and electron paramagnetic resonance (EPR) results 
      reveal that the *OH plays an important role in the 2,4-DCP degradation. The 
      fabricated photocatalyst can be utilized in the field of photocatalysis for 
      practical applications.
