摘要：
Nitrous oxide (N2O) is the third largest greenhouse gas after CO2 and CH4, and its capture has the dual value of resource recovery and greenhouse gas emission reduction. In this paper, MIL-101(Cr) with different anion terminals were synthesized by adding hydrofluoric acid and hydrochloric acid separately, named MIL-101(Cr)-F and MIL-101(Cr)-Cl, the synthesized samples were characterized by XRD, BET and SEM, et al. Single component adsorption isotherms of N2O and N2 were tested, and the selectivity of N2O/N2 and corresponding adsorption heat of gases were also calculated. Additionally, the simulation of mixture (N2O/N2=0.1%/99.9%) breakthrough were carried out. As the result, MIL-101(Cr)-Cl with the highest N2O adsorption capacity (6.43 mmol/g, 298 K) and N2O/N2 selectivity (267) were reported. Furthermore, the simulation result confirmed that MIL-101(Cr)-Cl has great potential to capture trace amount of N2O. © 2021, Editorial Board of CIESC Journal. All right reserved.
