Zeolite membrane with sub-nanofluidic channels for superior blue energy harvesting.

Blue energy, a clean energy source derived from salinity gradients, has recently drawn increased research attention. It can be harvested using charged membranes, typically composed of amorphous materials that suffer from low power density due to their disordered structure and low charge density. Crystalline materials, with inherently ordered porous structures, offer a promising alternative for overcoming these limitations.

Carbon nanotube supported oriented metal organic framework membrane for effective ethylene/ethane separation.

Zeolitic imidazolate framework 8 (ZIF-8) is effective for CH/CH separation because of the "sieving effect" of a six-membered (6-M) window. Here, we demonstrate that ZIF-8 is a versatile material that could effectively separate CH from CH via its 4-M window along the <100> direction. We established a facile and environmentally friendly carbon nanotube (CNT)-induced oriented membrane (CNT-OM) approach to fabricate a {100}-oriented ZIF-8 membrane (100-M).
