Ion transport is crucial for biological systems and membrane-based technology. Atomic-thick two-dimensional materials, especially graphene oxide (GO), have emerged as ideal building blocks developing synthetic membranes ion transport. However, the exclusion of small ions in a pressured filtration process remains challenge GO membranes.
