Abstract

Membranes, methods of making the membranes, and methods of using the membranes are described herein. The membrane can include a support layer, and a selective polymer layer disposed on the support layer. The selective polymer layer can include a selective polymer matrix (e.g., hydrophilic polymer, a cross-linking agent, an amino compound, a CO-philic ether, or a combination thereof), and optionally graphene oxide dispersed within the selective polymer matrix. The membranes can be used to separate carbon dioxide from hydrogen. Also provided are methods of purifying syngas using the membranes described herein.
