AB  - Herein, we report for the first time the highly efficient degradation of 
      2,4-dichlorophenol (2,4-DCP) over CeO(2)/g-C(3)N(4) composites (xCeO/CN) prepared 
      via wet-chemical solution method. It is shown that the resultant nanocomposites 
      with a proper mass ratio percentage (15%) of CeO coupled exhibit greatly enhanced 
      visible-light activity for 2,4-dichlorophenol (2,4-DCP) degradation compared to 
      the bare g-C(3)N(4). From photoluminescence (PL) and Fluorescence (FL) results, 
      it is suggested that enhanced photo-degradation is attributed to the 
      significantly improved charge separation and transfer as a result of the proper 
      band alignments between g-C(3)N(4) and CeO components. Further, from radical 
      trapping experiments, it is confirmed that hydroxyl radicals (OH) are the 
      predominant oxidants involved in the degradation of 2,4-DCP over CeO/CN 
      composites. Furthermore, a possible reaction pathway and detailed photocatalytic 
      mechanism for 2,4-DCP degradation is proposed mainly based on the detected liquid 
      chromatography tandem mass spectrometry (LC-MS) intermediate products, that 
      readily transform into CO(2) and H(2)O. This work would help researchers to 
      deeply understand the reaction mechanism of 2,4-DCP and would provide feasible 
      routes to fabricate g-C(3)N(4)-based highly efficient photocatalysts for 
      environmental remediation.
