AB  - Combination of microbial fuel cell (MFC) and advanced oxidation process (AOP) is 
      promising for pollutant removal. In this paper, Cu(0)-loaded carbon cloth cathode 
      by electrodeposition (Cu@CC-PS-MFC) was applied to enhance 2,4-dichlorophenol 
      (2,4-DCP) degradation based on persulfate (PS) activation in microbial fuel cell. 
      Cu(0) exhibited a typical structure of face-centered cubic metal polyhedron on 
      carbon cloth. The removal of 2,4-DCP by Cu@CC-PS-MFC (75.6%) was enhanced by more 
      than 50% compared to CC-PS-MFC (49.2%) after 1 h of reaction. 30 mg/L 2,4-DCP in 
      Cu@CC-PS-MFC was completely removed and achieved a high mineralization (80.6%) 
      after 9 h of reaction under optimized condition with low dissolved copper ion 
      concentration (0.615 mg/L). Meanwhile, more than 90% removal of 2,4-DCP was 
      stably achieved with flow operation condition (hydraulic residence time of 
      7.2 h). The change of copper valent state Cu(0)/Cu(2)O/CuO was the main mechanism 
      of PS activation with main reactive species of O*H and O(2)1. The bioanode of MFC 
      enhanced the in-situ regeneration of  identical withCu(+) and  identical withCu(0) on the catalyst surface by 
      transporting electrons, which was believed to contribute to good catalyst 
      lifetime and excellent 2,4-DCP removal. Electrodeposited copper contributes to 
      the enhanced degradation of 2,4-DCP with energy recovery at the same time which 
      can further broaden the application MFC.
