A supported Cu(I)@MIL-100(Fe) adsorbent was developed for the separation of CO/N2 binary gas mixture. The Cu(I)@MIL-100(Fe) was prepared by the wetness impregnation of the divalent copper salts on MIL-100(Fe); followed by the reduction of Cu2+→Cu+ under vacuum at elevated temperature. The samples were characterized by N2 adsorption; X-ray diffraction (XRD); X-ray photoelectron spectroscopy (XPS) and Fourier transform infrared spectroscopy (FTIR). The adsorption isotherms of CO and N2 on Cu(I)@MIL-100(Fe) were measured by the volumetric method; and the CO/N2 adsorption selectivities of the samples were calculated based on ideal adsorbed solution theory (IAST). The results showed that (a) the Cu(I)@MIL-100(Fe) adsorbent achieved a superior CO adsorption capacity of 2.78mmol/g at 298K and 100kPa; 7 times of that on parent MIL-100(Fe); and the adsorption behavior was well described by the dual-site Langmuir-Freundlich model; (b) the CO/N2 adsorption selectivity of Cu(I)@MIL-100(Fe) was up to 169 at 100kPa; being 112 times of that of parent MIL-100(Fe); (c) the significant enhancement of CO uptake and CO/N2 selectivity can be mainly attributed to the selective π-complexation between CO and Cu(I) on Cu(I)@MIL-100(Fe). © 2015 Elsevier B.V;
