Summary: The fabrication of advanced membranes with simultaneously high electron and proton conductivities has been achieved through the thermal reduction and vertical confinement of graphene oxide (GO) channels. The improvement in electron conductivity is due to the removal of oxygen functional groups, while the extremely reduced channel size allows for selective proton transport and improved proton selectivity.

Summary: In this study, SFZIF-8 was synthesized and found to have a higher adsorption performance for both Pb(II) and TC compared to commonly used adsorbents. The adsorption behaviors were explained by electrostatic attraction, surface complexation, hydrogen bonding, and 7C-7C interactions. SFZIF-8 nanocomposites can be utilized as alternative and promising adsorbents for the simultaneous removal of both Pb(II) and TC.

Summary: Subnanometer interlayer space in graphene oxide (GO) laminates is important for permselective membrane nanochannels. The precise control of nanochannel space and the role of confined nanochannel chemistry in selective water/ion separation are still challenging. This study used macrocyclic molecules with consistent basal plane but varying side groups to modify nanochannels in GO laminates, and demonstrated the side-group dependence of angstrom-precision tunability for channel free space and the energy barrier setting for ion transport. The study provides insights into functional-group-dependent intercalation modifications of GO laminates for structural control and nanochannel design.

Summary: By using a selective tearing method, nano-incised graphene kirigami (STGK) membranes with ultra-high water permeability have been fabricated. The results show that periodic wrinkles can be generated on defective graphene through the selective tearing method, leading to the breakage of C-C bonds and the formation of nano-incisions. The desalination simulation demonstrates that the STGK membrane achieves a water permeability of 1197 L/m2/h/bar with 100% salt rejection, surpassing nanoporous graphene and current reverse osmosis membranes by 5.2-6.3 times and more than two orders of magnitude, respectively. This work is expected to inspire the development of next-generation separation and purification membranes.
