Microporous framework membranes such as metal–organic framework (MOF) membranes
and covalent organic framework (COF) membranes are constructed by the controlled growth …

Helium is an unrenewable noble gas produced from natural gas with a wide range of
scientific, medical, and industrial applications. Due to the large differences in the kinetic …

The inherent inertness and striking physicochemical similarities of krypton and xenon pose
significant challenges to their separation. Reported herein is the efficient xenon capture and …

Molecular sieving membranes with uniform pore size are highly desired for carbon dioxide
separation. All-silica zeolite membranes feature well-defined micropores, but the size …

Porous and crystalline materials such as zeolites and metal-organic frameworks (MOFs)
have expanded the scope of membrane materials. In this review, we focus on the state-of …

Abstract All-silica Decadodecasil 3 R (DD3R) zeolite membranes, possessing small pore
size of 0.36 nm× 0.44 nm, have been attractive in CO 2 removal from natural gas. In this …

Nanoporous membranes based on two dimensional materials are predicted to provide
highly selective gas transport in combination with extreme permeance. Here we investigate …

Xe is an ideal anesthetic gas, but it has not been widely used in practice due to its high cost
and low output. Closed‐circuit Xe recovery and recycling is an economically viable method …

Crystalline porous materials (CPMs) with uniform and regular pore systems show great
potential for separation applications using membrane technology. Along with the research …

Efficient hydrogen (H 2) separation is highly desired from the cracked tail gas of ethylene
plant. In this work, DD3R zeolite membranes have been evaluated for potential application …
