C 3 H 6 /C 3 H 8 Adsorption Behavior Study of Stiffened ZIF‐8 Prepared under an Electric Field

Metal‐organic frameworks (MOFs) show great potential for adsorption separation. However, MOFs' flexibility may influence their adsorption behaviors. Here, for the first time we prepare ZIF‐8 powder dominated with stiffened ZIF‐8_Cm phase under an external E‐field. By comparison, we find that th...

Summary:Metal‐organic frameworks (MOFs) show great potential for adsorption separation. However, MOFs' flexibility may influence their adsorption behaviors. Here, for the first time we prepare ZIF‐8 powder dominated with stiffened ZIF‐8_Cm phase under an external E‐field. By comparison, we find that the flexibility of ZIF‐8 has little influence in equilibrium‐based separation behavior for C 3 H 6 /C 3 H 8 . However, the stiffened ZIF‐8 formed in E‐field presents an obviously decreased diffusion rate for C 3 H 8 , whose C 3 H 6 /C 3 H 8 kinetic‐based separation factor is around 2.5 times higher than that of the traditional ZIF‐8 powder.
