Abstract

CuCl impregnated MIL-100(Cr) was prepared with a facile method and then utilized for the adsorptive denitrogenation of model fossil fuels. CuCl was produced from CuCl₂ solution at ambient temperature and pressure by reduction of CuCl₂ using sodium sulfite as a mild reducing agent. Although the porosity of the adsorbent was reduced after impregnation, the adsorption of nitrogen-containing compounds (NCCs) increased. However, the adsorption of NCCs over CuCl₂/MIL-100(Cr), which was produced in a similar manner but in the absence of Na₂SO₃, was decreased as a result of the reduced porosity. The maximum adsorption capacities of CuCl/MIL-100(Cr) as compared to pristine MIL-100(Cr) for quinoline (QUI) and indole (IND) were improved by 9% and 15%, respectively, which may be attributed to the π-complexation effect of the Cu⁺ sites of CuCl.
