The high performance of two-dimensional (2D) channel membranes is generally achieved by preparing ultrathin or forming short channels with less tortuous transport through self-assembly of small flakes. Here, the authors report the construction of vertical channels in graphene oxide membranes based on a substrate template with asymmetric pores demonstrating high flux and metal ion rejection.
