Abstract
En 中文
• A novel cationic AB-stacking COF (EB-COF) bilayer tackles the permeability-selectivity challenge. • The EB-COF bilayer membrane achieves a record 7,174 W m−2 power output, outperforming older designs. • Tiny sub-2 nm pores and high charge density enhance both ion flow and selectivity for better performance. • This study offers fundamental insights into the structure-performance relationship of permselective membranes.
