Dynamic Electrophoretic Assembly Coupled With Water‐Splitting‐Induced pH Control Enables Precision Ion Sieving Membranes

Advanced Materials, EarlyView.
A green, external‐catalyst‐free route grows defect‐free covalent organic framework membranes directly on ion‐exchange supports using an alternating electric field and in situ‐generated acid. Through a self‐regulating, self‐healing mechanism, the membranes achieve near‐complete, ultra‐fast separation of monovalent ions such as Li+, Na+, and K+, offering

Integrated Bipolar Membrane Electrodialysis and Electrolysis for CO2 Capture and Conversion

Advanced Energy Materials, EarlyView.
This work demonstrates an integrated BMEED platform that couples CO2 capture and conversion within a single modular system. By combining BMED with CO2E, high‐purity CO is produced while avoiding intermediate stripping, excessive capital and O&M costs, and external gas feeds.

Ion selectivity of graphene nanopores

Nature Communications, 2016
Sub-nanometer graphene nanopores are usually required to create graphene-based reverse osmosis membranes. Here, Rollings et al.show that membranes with larger pores are highly ion selective and a hundred times more permeable to potassium ions than to ...
