AB  - It has been clearly demonstrated that the visible-light photocatalytic activities 
      of g-C(3)N(4) (CN) for degrading 2,4-dichlorophenol (2,4-DCP) and bisphenol A 
      (BPA) could be improved by fabricating nanocomposites with a proper amount of 
      nanocrystalline anatase TiO(2). Interestingly, the visible-light activities of 
      the amount-optimized nanocomposite could be further improved after decorating Au 
      nanoparticles, with 5.11- and 3.1-time improvement respectively for 2,4-DCP and 
      BPA compared to that of CN, even much higher than that of P25 TiO(2) under UV-vis 
      irradiation. Based on the transient-state surface photovoltage responses and 
      photoelectrochemical measurements, it is confirmed that the exceptional 
      visible-light activities of the fabricated Au-(TiO(2)/g-C(3)N(4)) nanocomposites 
      are attributed to the extended visible-light response due to the surface 
      plasmonic resonance (SPR) of decorated Au and its catalytic function, and to the 
      enhanced charge separation by transferring electrons from CN and SPR Au to TiO(2) 
      in the nanocomposites. The highly promoted charge separation results in the 
      effective availability of a large number of hydroxyl radicals (OH) participating 
      in the photocatalytic oxidation process of 2,4-DCP. Furthermore, a possible 
      mechanism of 2,4-DCP degradation is proposed according to the detailed analyses 
      of produced intermediates. This work provides new idea for designing Au assisted 
      nanocomposite photocatalysts for environmental remediation.
