| 摘要: 合成3种具有不同取代基（—X）的金属有机骨架（MOFs）材料CAU-10-X（X=H、NO2、CH3），研究了从N2O/N2混合物中吸附捕获N2O的性能。综合单组分吸附等温线、吸附热和IAST（理想溶液吸附理论）选择性的实验结果，发现CAU-10-NO2在低压区的N2O吸附量明显高于母体CAU-10-H，其可以有效地从N2O/N2混合物中捕集N2O，而CAU-10-CH3则表现出相反的效果。N2O/N2混合物的穿透模拟进一步证明CAU-10-NO2对微量N2O具有较好的捕获能力，循环实验显示该材料具有良好的稳定性。 |

| Abstract: Three metal-organic frameworks (MOFs) materials, CAU-10-X (X=H, NO 2, CH3), with different substituents (-X) were synthesized and the adsorption and capture properties of N2O from N2O/N2 mixtures were studied. Considering the experimental results of single-component adsorption isotherm, adsorption heat, and IAST (ideal adsorbed solution theory) selectivity, we found that the adsorption capacity of CAU-10-NO2 was significantly higher than that of the parent CAU-10-H in the low-pressure region, and it could effectively capture N2O from the N2O/N2 mixture, while CAU-10-CH3 showed the opposite effect. The penetration simulation of N2O/N2 mixture further proved that CAU-10-NO2 had a good ability to capture trace N2O, and the cycle experiment showed that CAU-10-NO2 had good stability. |
