Abstract:

Two-dimensional(2D) materials have been widely studied due to their unique characteristics including large spe-cific surface area,highly anisotropy and large aspect ratio.The interlayer spacings of lamellar membranes assembled by two-dimensional materials can be used as the nanochannels for the ion selective transport,it can realize controllable ion sieving and energy storage and conversion.In addition,the transport behavior of ions inside the channels depends on the structures and surface chemistry of the 2D building blocks.Taking several typical 2D materials for examples,this review elaborated the research progress including assembly methods,structures,ion transport properties and the alternation strategies of these 2D nanofluidic channels,and further focused on their applied research in the fields of energy storage and conversion and ion sieving.Furthermore,the critical scientific issues of the 2D nanofluidic channels in real application were refined and conclud-ed.The factors that limited the real application of the two-dimensional nanofluidic channels were pointed out,and correspond-ing strategies were also provided.Finally,the future development of the 2D nanofluidic channels in practical applications were prospected.

Key words: two-dimensional nanomaterials, nanofluidic, ionic selectivity
