A novel hydrophobic adsorbent, Cu-BTC-(n)Br, was successfully synthesized by Cu(NO3)(2) (metal ions source) and BTC-(n)Br (organic ligand) using a hydrothermal synthesis technology. Nitrogen adsorption-desorption, X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared (FT-IR), and water contact angle are employed to characterize our obtained materials. Successful modification of these certain materials has been confirmed and the structural changes of them have been further explored. The efficient adsorption properties of as-prepared adsorbents for thiophene were evaluated by means of batch experiments. Compared with undressed Cu-BTC, Cu-BTC-(n)Br showed distinguished hydrophobicity and remarkable ad-sorption effectivity under aqueous circumstance. In addition, the adsorption process performance could be perfectly described by Langmuir adsorption model and pseudo-second-order equation. The hydrophobic Cu-BTC-(n)Br material might be a hopeful desulphurizer for real fuel in the presence of moisture.
