Description
Chiral enantiomers are mirror images with identical physical properties yet divergent biological activities, making their efficient separation a fundamental challenge. Graphene oxide (GO) membranes possess tunable lamellar nanochannels that enable molecular sieving; however, existing chiral GO membranes remain limited by low separation factors (≤4.76)[1]. Here, we report a proline-functionalized GO membrane that leverages differential adsorption energies between the chiral channel walls and enantiomers, achieving a separation factor of 20.1 and a flux of 4.5 mmol m⁻² h⁻¹, substantially surpassing the state-of-the-art.
