Designing Biomimic Two-Dimensional Ionic Transport Channels for Efficient Ion Sieving

Mengchen Zhang et al.

Summary: A biomimetic 2D ionic transport channel system based on graphene oxide (GO) membrane was designed, inspired by biological ion channels, showing exceptional K+ transport rate and competitive selectivity. The efficient ion sieving with the ionic GO membrane is achieved through high diffusion and partition coefficients of hydrated monovalent ions, as well as large energy barrier and limited potential gradient of hydrated divalent ions.

Precise Sub-Angstrom Ion Separation Using Conjugated Microporous Polymer Membranes

Zongyao Zhou et al.

Summary: Polymer membranes usually have a wide pore-size distribution, resulting in lower selectivity in ion separation compared to membranes made of crystalline porous materials. However, ion-sieving membranes based on conjugated microporous polymers with high uniform sub-nanometer pores can achieve high ion-separating performance with a sub-1 A size precision, attributed to their uniform and narrow pore-size distribution.

Homointerface covalent organic framework membranes for efficient desalination

Jianliang Shen et al.

Summary: In this study, a series of bilayer COF membranes with homointerface and heterointerface were designed, achieving efficient desalination performance through manipulating the interface confinement effect. The rejection rate of homointerface COF membrane toward Na2SO4 was higher than that of heterointerface COF membranes due to the synergistic enhancement of interface-confined size sieving and Donnan effect. The homointerface TpPa-SO3H/TpPa-SO3H/MPAN membrane exhibited the highest reported performance among COF desalination membranes, with a rejection rate of 98.3% for Na2SO4 and water flux of 13.1 L m(-2) h(-1) bar(-1).
