May 1, 2010 · Continuous and c-oriented ZIF-69 membranes were successfully synthesized on porous α-alumina substrates by an in situ solvothermal method. The membranes were characterized by XRD, SEM and single-gas permeation tests.

Feb 15, 2008 · The adsorption isotherms for all three ZIFs show a disproportionately high affinity and capacity for CO 2 (SOM text S5), with ZIF-69 outperforming ZIF-68 and ZIF-70, as well as the state-of-the-art material BPL carbon (Table 2 and Fig. 2B).

Jul 1, 2017 · The obtained ZIF-69 exhibited a higher adsorption capacity of C 2 H 6 over C 2 H 4 at 100 kPa, and the C 2 H 6 /C 2 H 4 adsorption selectivity was about 1.7 at below 100 kPa. The outcome would provide a new insight into the study on the effective separation of ethane/ethylene using different topological structures of ZIFs.

Sep 1, 2011 · In this study we target to extend the seeded growth method to the synthesis of ZIF-69 membranes. ZIF-69 has a zeolite GME topology that has 12-membered ring (MR) straight channels along the c -axis and 8 MR channels along the a - and b -axes. The pore size along the c -axis is about 0.78 nm.

Dec 13, 2022 · XRD has characterized the ZIF-69 membrane, and the pattern has confirmed the pure phase of ZIF-69 . The XRD patterns for ZIF-78 have confirmed its crystalline phase . Similarly, their XRD patterns confirmed the successful syntheses of ZIF-90 and 91 .

Aug 2, 2013 · Zeolitic imidazolate framework ZIF-69 membranes were grown on porous α-alumina substrates via seeded secondary growth and further functionalized by a CO 2-selective tricyanomethanide anion/alkylmethylimidazolium cation-based ionic liquid (IL) to plug the gaps between the ZIF crystals yet leave the framework pores open for gas diffusion.

Abstract: A high-throughput protocol was developed for the synthesis of zeolitic imidazolate frameworks (ZIFs). Twenty-five different ZIF crystals were synthesized from only 9600 microreactions of either zinc (II)/cobalt (II) and imidazolate/imidazolate-type linkers.

We focus the synthesized ZIF-69 membranes on separating C5–C7 hydrocarbon mixtures, and the membranes show strong potential for applying in gasoline vapor recovery.

Jun 20, 2015 · We focus the synthesized ZIF-69 membranes on separating C5–C7 hydrocarbon mixtures, and the membranes show strong potential for applying in gasoline vapor recovery.

Sep 19, 2016 · According to batch adsorption performances and modeling, ZIF-8 exhibits the highest adsorption selectivity and capacity for nHEX, followed by ZIF-69 and 5A zeolite. The equilibrium data at 25 °C show that a significant amount (0.51 g/g) of n HEX and only 0.09 g/g 2MP can be adsorbed in ZIF-8.
