High-Flux Membranes Based on the Covalent Organic Framework COF-LZU1 for Selective Dye Separation by Nanofiltration.
TL;DR: The continuous two-dimensional imine-linked COF-LZU1 membrane with a thickness of only 400 nm was prepared on alumina tubes by in-situ solvothermal synthesis and shows excellent water permeance and outstanding water stability, rendering it an interesting system for water purification.
Journal ArticleDOI
Covalent Organic Framework–Covalent Organic Framework Bilayer Membranes for Highly Selective Gas Separation

TL;DR: A new type of a two-dimensional layered-stacking COF-COF composite membrane in bilayer geometry synthesized on a porous support by successively regulating the growth of imine-based COf-LZU1 and azine- based ACOF-1 layers via a temperature-swing solvothermal approach is demonstrated.
Journal ArticleDOI
Robust Superhydrophobic/Superoleophilic Wrinkled Microspherical MOF@rGO Composites for Efficient Oil–Water Separation
TL;DR: Novel wrinkled 3D microspherical MOF@rGO composites with both superhydrophobic and superoleophilic properties were developed by embedding MOF nanoparticles between graphene oxide (GO) nanosheets, followed by high-temperature reduction self-assembly.
Journal ArticleDOI
High-Flux Vertically Aligned 2D Covalent Organic Framework Membrane with Enhanced Hydrogen Separation.
TL;DR: A new concept of vertically aligned 2D COF layers forming a membrane for efficient gas separation on the basis of precise size exclusion is proposed, which exhibits a high H2 permeability together with a desirable separation selectivity for gas mixtures such as H2/CO2 and H2-CH4.
Journal ArticleDOI
MOF-in-COF molecular sieving membrane for selective hydrogen separation.
TL;DR: In this paper, a MOF-in-COF concept was proposed for the confined growth of metal-organic framework (MOFs) inside a supported COF layer to prepare MOF in COF membranes, which exhibited an excellent hydrogen permeance (>3000 GPU) together with a significant enhancement of hydrogen over other gases.
