We report here on the removal of alkylphenols (phenol, 4-n-propylphenol, 4-nheptylphenol and 4-nonylphenol) dissolved in water using the composite particles of nanocrystalline titania and alkyltrimethylammonium bromide (C n H 2n+1 N(CH 3 ) 3 Br, C n TAB; n = 12, 14, 16 and 18) (named as TiO 2 /C n TAB Nanoskeleton) as adsorbents and photocatalysts. In particular, the adsorption of alkylphenols onto TiO 2 /C n TAB Nanoskeleton in water was investigated in terms of hydrophobic interaction between alkylphenols and C n TAB, surface area, pore structure and crystal size of TiO 2 /C n TAB Nanoskeleton.We revealed that C n TAB incorporated in the TiO 2 /C n TAB Nanoskeleton promotes the adsorption of alkylphenols onto TiO 2 /C n TAB Nanoskeleton due to the hydrophobic interaction between alkylphenols and C n TAB.On the other hand, the surface area, pore structure and crystal size of TiO 2 /C n TAB Nanoskeleton did not affect the adsorption of alkylphenols onto TiO 2 /C n TAB Nanoskeleton. We also found that the alkylphenols dissolved in water were completely removed by the combination of adsorption and photocatalytic degradation by the TiO 2 /C n TAB Nanoskeleton under UV irradiation. These results prove that the TiO 2 /C n TAB Nanoskeleton acts as in tandem an adsorbent and a photocatalyst for removal of alkylphenols dissolved in water.
