Due to their tunable nanostructure, graphene oxide membranes (GOMs) have attracted numerous researchers in the water purification fields. However, the practical application of GOMs has been impeded by their low flux and tendency to swell during operation. In this work, we intercalated GOMs with N-doped graphene (NG), which possesses a higher water dispersibility compared to unmodified graphene, to simultaneously improve its stability, water permeability, and water/dye separation ability. The composite GO-NG membrane (GNM) enhanced the water flux to approximately 3 times higher than that of GOM, with higher than 98% rejection for various dyes. GNM remained stable during this purification.
