AB  - The immobilization of pre-dispersed TiO2 colloids onto the external surface of 
      the clay mineral montmorillonite (Mt) was accomplished and regulated via a 
      self-assembly method employing the cationic surfactant cetyltrimethylammonium 
      bromide (CTAB). The role of CTAB in the synthesis process was investigated by 
      preparing a series of TiO2-CTAB-Mt composites (TCM) with various CTAB doses. The 
      results indicated that a uniform and continuous TiO2 film was deposited on the 
      external surface of montmorillonite in the composite synthesized with 0.1 wt.% of 
      CTAB, and the TCM nano-composites showed much higher values for specific surface 
      area, average pore size and pore volume than the raw montmorillonite clay. Then, 
      the formed TCM materials were applied in photocatalytic degradation of 
      2,4-dichlorophenol (2,4-DCP) in aqueous solution. The degradation efficiency 
      reached as high as 94.7%. Based on the degradation intermediates benezoquinone, 
      fumaric acid and oxalic acid identified by LC-MS analysis, a mechanism for the 
      photocatalytic oxidation of 2,4-DCP on TiO2/Mt nano-composites is proposed.
