Abstract
Membranes, methods of making the membranes, and methods of using the membranes are described herein. The membrane can comprise a support layer; and a selective polymer layer disposed on the support layer. The selective polymer layer can comprise a selective polymer matrix (e.g., hydrophilic polymer, an amine-containing polymer, a low molecular weight amino compound, a CO2-philic ether, or a combination thereof), and graphene oxide dispersed within the selective polymer matrix. The membranes can be used to separate carbon dioxide for hydrogen. Also provided are methods of purifying syngas using the membranes described herein.
Claims19
A membrane comprising:
