Recent Progress on Microfine Design of Metal–Organic Frameworks: Structure Regulation and Gas Sorption and Separation

Advanced Materials, Journal Year: 2020, Volume and Issue: 32(44)

Published: July 16, 2020

Metal-organic frameworks (MOFs) have emerged as an important and unique class of functional crystalline hybrid porous materials in the past two decades. Due to their modular structures adjustable pore system, such distinctive exhibited remarkable prospects key applications pertaining adsorption gas storage, liquid separations, trace impurity removal. Evidently, gaining a better understanding structure-property relationship offers great potential for enhancement given associated MOF property either by structural adjustments via isoreticular chemistry or design construction new practice reticular chemistry. Correspondingly, application paves way microfine structure regulation presented MOFs. Explicitly, tuning is mainly based on known platforms, focusing modification and/or functionalization precise part thus providing effective approach produce richer systems with enhanced performances from limited number platforms. Here, latest progress this field highlighted emphasizing differences connections between various methods. Finally, challenges together are also discussed.

An Ultramicroporous Metal–Organic Framework for High Sieving Separation of Propylene from Propane

Journal of the American Chemical Society, Journal Year: 2020, Volume and Issue: 142(41), P. 17795 - 17801

Published: Sept. 29, 2020

Highly selective adsorptive separation of olefin/paraffin through porous materials can produce high purity olefins in a much more energy-efficient way than the traditional cryogenic distillation. Here we report an ultramicroporous cobalt gallate metal-organic framework (Co-gallate) for highly sieving propylene/propane at ambient conditions. This material possesses optimal pore structure exact confinement propylene molecules while excluding slightly large propane molecules, as clearly demonstrated neutron diffraction crystal Co-gallate⊃0.38C

Tuning Gate‐Opening of a Flexible Metal–Organic Framework for Ternary Gas Sieving Separation

Angewandte Chemie International Edition, Journal Year: 2020, Volume and Issue: 59(50), P. 22756 - 22762

Published: Sept. 2, 2020

In comparison with the fast development of binary mixture separations, ternary separations are significantly more difficult and have rarely been realized by a single material. Herein, new strategy tuning gate-opening pressure flexible MOFs is developed to tackle such challenge. As demonstrated framework NTU-65, ethylene (C2 H4 ), acetylene H2 carbon dioxide (CO2 ) can be regulated temperature. Therefore, efficient sieving separation this was realized. Under optimized temperature, NTU-65 adsorbed large amount C2 CO2 through only negligible . Breakthrough experiments that material simultaneously capture , yielding polymer-grade (>99.99 %) from breakthrough separation.

Purification of C2H4 from a ternary C2H2/C2H6/C2H4 mixture by one-step adsorption separation is prime importance but challenging in the petrochemical industry; however, effective strategies to design high-performance adsorbents are lacking. We herein report for first time incorporation Lewis basic sites into C2H6-selective MOF, enabling efficient production polymer-grade mixtures. Introduction amino groups highly stable UiO-67 can not only partition large pores smaller cagelike pockets provide suitable pore confinement also offer additional binding simultaneously enhance C2H2 and C2H6 capacities over C2H4. The amino-functionalized UiO-67-(NH2)2 thus exhibits exceptionally high uptakes as well benchmark C2H2/C2H4 C2H6/C2H4 selectivities, surpassing all C2H2/C2H6-selective materials reported so far. Theoretical calculations combined with situ infrared spectroscopy indicate that synergetic effect functional surfaces decorated provides overall stronger multipoint van der Waals interactions exceptional performance was evidenced breakthrough experiments mixtures under dry wet conditions, providing remarkable productivity 0.55 mmol g-1 at ambient conditions.
