Regularly channeled MXene membranes for ionic and molecular separation
Membrane-based separation technologies,compared with other traditional separation operations such as evaporation,extraction,precipitation and distillation,have the merits of low energy consumption,small land footprint and high efficiency and have,therefore,attracted wide attention in past decades[1,2].Laminar membranes formed by two-dimensional(2D)nanosheet stacking showed high flex-ibility in adjusting the subnanoscale interlayer spacing to allow the unhindered transport of small ions or molecules,demonstrating high separation performance and economic applicability[3].Graphene oxide(GO)membranes have been applied in seawater desalination,gas separation,nanofiltration,and ultrafiltration[4,5].However,the intrinsic flexibility of GO nanosheets may lead to the formation of random laminar structures if stacked into membranes,which limits their selectivity[6,7].Therefore,the fabrication of nanoconfined highly ordered separation membranes with regular 2D nanochannels is the key to efficient and stable separation capability.
