摘要：
This work investigates the adsorption performance of adsorbent MOF-74(Ni) for CO/N2 and CO2/CO2 binary gas mixtures. Adsorbent MOF-74(Ni) with high density of coordinatively unsaturated sites was synthesized by a hydrothermal method, and characterized with N2 adsorption, P-XRD, and SEM. The adsorption isotherms of CO, N2 and CO2 on MOF-74(Ni) were measured, and the selectivities for CO/N2 and CO/CO2 were calculated based on ideal adsorbed solution theory (IAST). Results showed that adsorbent MOF-74(Ni) achieved superior CO adsorption capacity of 6.15 mmol·g-1 at 298 K and 0.1 MPa, and as low as 0.86 mmol·g-1 for N2. In low pressure range of 0-40 kPa, MOF-74(Ni) showed significantly higher uptake for CO than that for CO2. Moreover, IAST-predicted CO/N2 selectivity of MOF-74(Ni) is above 1000, and its CO/CO2 selectivity is in the range of 4-9. It suggests that MOF-74(Ni) is more favorable for CO adsorption than N2 and CO2 adsorption. © All Right Reserved.
