Removal of sulfur-containing compounds from fuels like diesel and gasoline to a low level before utilization has become a great challenge [1]. MIL-100-Fe, one of the typical metal-organic frameworks [2, 3], has been used for the first time as support materials for Cu+ species, which were obtained from one-step synthesis of Cu2O particles at low temperature. The Cu+-loaded MOFs were evaluated as efficient adsorbents for the liquid-phase adsorption of benzothiophene (BT) [4]. The effect of Cu+ loading on the adsorption kinetics and maximum adsorption capacity (Q0) for the adsorption of BT was also studied. The maximum adsorption capacity (Q0) increased with increasing copper loading up to a Cu/Fe (wt./wt.) ratio of 0.07 in Cu+-loaded-MIL-100-Fe, resulting in an increase in the Q0 by 14% compared with the virgin MIL-100-Fe without Cu+ ions. Since the surface area and pore volume decrease with the loading of copper, the increased Q0 over the Cu+-loaded MIL-100-Fe adsorbents suggests specific favorable interactions (probably by π-complexation) between Cu+ and BT.
