AB  - A single-chamber bio-photoelectrochemical system (BPES) constructed with 
      BiVO(4)/reduced graphene oxide (RGO) photocathode was proposed for 
      2,4-dichlorophenol (2,4-DCP) degradation under simulated solar irradiation. The 
      BiVO(4)/RGO (B/G) composites were synthesized, optimized and characterized by 
      various techniques to analyze their physico-chemical and photocatalytic 
      properties. Results showed that B/G (5 wt% - 9 h - 150  degrees C) exhibited the best 
      photocatalytic activity for 2,4-DCP degradation, which was 1.5 times of that of 
      BiVO(4), due to its better light absorption, faster electrons transfer, and more 
      efficient photo-generated e(-) - h(+) separation. Reactive species trapping 
      experiments revealed that .OH was the main radical leading to 2,4-DCP 
      degradation, and h(+) also influenced 2,4-DCP removal. The 2,4-DCP (20 mg/L) 
      removal rate and current output from the illuminated BPES were much higher than 
      those of the unilluminated reactor (68.5 % vs. 41.8 %, 60.31 A/m(3) vs. 40.07 
      A/m(3)) in 24 h, and the cathode potential was more negative, indicating that 
      photocathode catalytic process was favorable to pollutants degradation and energy 
      generation. Intermediates of 2,4-DCP degradation in the BPES were identified, and 
      accordingly, possible degradation pathway and mechanism were proposed. This 
      research advanced the development of efficient photocathode and mechanism of 
      recalcitrant wastewater treatment in the BPES.
