Water Purification: Charged Layered Boron Nitride‐Nanoflake Membranes for Efficient Ion Separation and Water Purification (Small 49/2019)

In article number 1904590, Sangil Kim and co-workers present a 2D lamellar membrane synthesized using hexagonal boron nitride nanoflakes (h-BNF) for highly efficient ion separation. Water passes through the compact flow channels of the boron nitride nanoflake membrane whereas charged ions are efficiently blocked by the ionic size and the electrostatic repulsion between the membrane surface and the ions.
