摘要：Graphene oxide (GO) membranes have attracted a great deal of attention due to their unique two-dimensional (2D) structure and potential in separation processes. In complicated wastewater treatments, conventional GO-based membranes still suffer from a permeance and stability trade-off and thus cannot be widely used at present. In this study, we report a facile strategy to fabricate beta-cyclodextrin(beta-CD)-functionalized GO membranes (denoted as C-GO) with precisely engineered interlayer nanochannels. The resulting membranes achieved a water permeance of 370.7 L m -2 h-1 bar-1, which is 3.1 times higher than that of pristine GO membranes, while simultaneously maintaining excellent rejection of multivalent heavy-metal cations exceeding 99%. Moreover, the C-GO membranes demonstrate remarkable structural stability across a wide pH range (2-12) for over 21 days. Overall, our research demonstrates a promising avenue for the rational design of next-generation high-performance separation materials for industrial applications such as heavy-metal wastewater treatment, resource recovery, and fine chemical separations.
