[ASAP] Construction of Biomimetic Porous Membranes Inspired by Honeycomb for Selective Adsorption and Recovery of Rare Earth Ions

AI Insight

The study presents the development of biomimetic porous membranes modeled after honeycomb structures, designed for the selective adsorption and recovery of rare earth ions from aqueous solutions. The hexagonal, ordered pore architecture mimics the geometric efficiency of natural honeycombs, providing high surface area and structural regularity that enhances ion-selective binding. The membranes demonstrate selective capture of target rare earth ions, suggesting that pore geometry and surface functionalization work in concert to achieve separation performance.

Why it matters

Rare earth elements are critical components in electronics, renewable energy technologies, and defense applications, yet their extraction and recycling remain environmentally costly and inefficient. Membrane-based recovery systems of this kind could offer a more sustainable and scalable alternative to conventional solvent extraction or ion exchange methods.
