Graphene oxide membranes tuned by metal-phytic acid coordination complex for butanol dehydration

For two-dimensional (2D) lamellar graphene oxide (GO) membranes, tuning the interlayer distance and enhancing surface hydrophilicity are two efficient strategies to achieve high selectivity and permeation flux for solvent dehydration. Herein, Fe3+-phytic acid (PA) coordination complex was designed as both the intercalator and surface modifier to fabricate hydrophilic GO membranes. Fe3+-PA complexes interacted with the oxygen-containing...
