AB  - A series of visible-light responsive photocatalysts prepared using Ag3PO4 
      immobilized with graphene oxide (GO) with varying GO content were obtained by an 
      electrostatically driven method, and 2,4-dichlorophenol (2,4-DCP) was used to 
      evaluate the performance of the photocatalysts. The composites exhibited superior 
      photocatalytic activity and stability compared with pure Ag3PO4. When the content 
      of GO was 5%, the degradation efficiency of 2,4-DCP could reach 98.95%, and 
      55.91% of the total organic (TOC) content was removed within 60 min irradiation. 
      Meanwhile, the efficiency of 91.77% was achieved for 2,4-DCP degradation even 
      after four times of recycling in the photocatalysis/Ag3PO4-GO (5%) system. 
      Reactive species of O2( -), OH  and h(+) were considered as the main participants 
      for oxidizing 2,4-DCP, as confirmed by the free radical capture experiments. And 
      some organic intermediates including 4-chlorophenol (4-CP), hydroquinone (HQ), 
      benzoquinone (BZQ), 2-chlorohydroquinone and hydroxyhydroquinone (HHQ) were 
      detected by comparison with the standard retention times from the high 
      performance liquid chromatography (HPLC). In short, the enhanced photocatalytic 
      property of Ag3PO4-GO was closely related to the strong absorption ability of GO 
      relative to 2,4-DCP, the effective separation of photogenerated electron-hole 
      pairs, and the excellent electron capture capability of GO.
