Published: Sept. 22, 2023

3D ionic covalent organic framework (COF) membranes, which are envisioned to be able break the trade-off between ion conductivity and selectivity, waiting for exploitation. Herein, we report fabrication of a sulfonic acid-functionalized COF membrane (3D SCOF) efficient selective transport, using dual acid-mediated interfacial polymerization strategy. The SCOF membranes possess highly interconnected transport channels, ultramicroporous pore sizes (0.97 nm), abundant sulfonate groups (with high exchange capacity 4.1 mmol g-1), leading proton 843 mS cm-1 at 90 °C. When utilized in osmotic energy conversion, power density 21.2 W m-2, remarkable selectivity 0.976 thus an exceptional conversion efficiency 45.3% simultaneously achieved. This work provides alternative approach promotes applications COFs separation.

An Ionic Diode Covalent Organic Framework Membrane for Efficient Osmotic Energy Conversion

ACS Nano, Journal Year: 2022, Volume and Issue: 16(11), P. 18910 - 18920

Published: Oct. 25, 2022

Heterogeneous membranes that exhibit an ionic diode effect are promising candidates for osmotic energy conversion. However, existing heterogeneous lack molecular-level designed ion channels, thereby limiting their power densities. Here, we demonstrate covalent organic framework (COF) with well-defined asymmetric geometry and surface charge polarity as high-performance generators. The COF comprised of heterojunctions combining a positively charged ultrathin layer negatively supported by porous nanofiber scaffold, exhibiting effectuates fast unidirectional diffusion anion selectivity. Density functional theory calculations reveal the differentiated interactions between anions channels contributed to superior I- transport over other anions. Consequently, achieved high output densities 19.2 210.1 W m-2 under 50-fold NaCl NaI gradient, respectively, outperforming state-of-the-art membranes. This work suggests great potential energy-related applications.
