It is critical to enhance further the stability and adsorption selectivity of MOFs for promoting applications of MOFs. Herein, we proposed an effective bifunctional SBU-tuning strategy to synthesize novel Pyr1/3@Cu–BTC for the separation of propylene/propane. [email protected] Cu–BTC was synthesized by grafting of pyrrole onto Cu–BTC. Its water vapor stability and separation property were then examined. The resulting Pyr1/3@Cu–BTC showed not only enhanced water vapor stability but also superhigh C3H6 adsorption capacity as well as C3H6/C3H8 selectivity at 1 bar and 298 K, reaching 7.60 mmol/g and 8.3 separately, much higher than most MOFs. Experiments of water vapor stability indicated that after being placed under humid air (RH of 55%) for 20 days, Pyr1/3@Cu–BTC still retained its crystalline structure. The application of the fixed bed of Pyr1/3@Cu–BTC could completely separate C3H6 and C3H8 from their mixture at ambient conditions. Pyr1/3@Cu–BTC is promising for the separation of propylene/propane or propylene recovery from dry gas.

室温合成具有增强稳定性的Pyr 1/3 @ Cu-BTC及其在分离丙烯/丙烷方面的优异性能
至关重要的是进一步增强MOF的稳定性和吸附选择性，以促进MOF的应用。在这里，我们提出了一种有效的双功能SBU调节策略，以合成用于分离丙烯/丙烷的新型Pyr 1/3 @ Cu-BTC。[受电子邮件保护]通过将吡咯接枝到Cu-BTC上来合成Cu-BTC。然后检查其水蒸气稳定性和分离性能。生成的Pyr 1/3 @ Cu-BTC不仅显示出增强的水蒸气稳定性，而且还具有超高的C 3 H 6吸附能力以及C 3 H 6 / C 3 H 8在1 bar和298 K下的选择性，分别达到7.60 mmol / g和8.3，远高于大多数MOF。水蒸气稳定性实验表明，将Pyr 1/3 @ Cu-BTC放在潮湿空气（相对湿度55％）中20天后仍保持其晶体结构。在环境条件下，使用Pyr 1/3 @ Cu-BTC固定床可以完全从混合物中分离出C 3 H 6和C 3 H 8。Pyr 1/3 @ Cu–BTC有望从干燥气体中分离出丙烯/丙烷或丙烯。
