Bottom-up synthesis of two-dimensional carbon with vertically aligned ordered micropores for ultrafast nanofiltration.

ABSTRACT: Two-dimensional (2D) carbon materials perforated with uniform micropores are considered ideal building blocks to fabricate advanced membranes for molecular separation and energy storage devices with high rate capabilities. However, creating high-density uniform micropores in 2D carbon using conventional perforation methods remains a formidable challenge. Here, we report a zeolite-templated bottom-up synthesis of ordered microporous 2D carbon. Through rational analysis of 255 zeolite structures, we find that the IWV zeolite having large 2D microporous channels and aluminosilicate compositions can serve as an ideal template for carbon replication. The resulting carbon is made of an extremely thin polyaromatic backbone and contains well-defined vertically aligned micropores (0.69 nm in diamet
