​Crumpled graphene oxide membranes could enable both permeability and selectivity of H2 and CO2 

Separating gases efficiently is important for applications like hydrogen production and carbon dioxide capture. Gas separation membranes, especially those made from graphene oxide (GO), show promise because they can selectively allow certain gases to pass through. However, conventional GO membranes currently face a major limitation: while they can separate gases like H2 and CO2, the rate at which gases move through these membranes is too slow for practical use.

Researchers at the National University of Singapore, Missouri University of Science and Technology and Radboud University have developed a new approach to creating crumpled GO membranes that exhibit both a higher H2 permeability and selectivity (i.e., ability to distinguish between different gases). Their method could facilitate the real-world use of these membranes to produce clean H2 and capture gases that are harmful for the environment.
