A Two‐Dimensional Laminated V₂O₅ Membrane for Metal Ions Separation

Zhang, Yating / Zhang, Zhenxin / Zhu, Qianqian / Fang, Wei

A new kind of lamellar membrane based on V₂O₅ nanosheets supported on anodic aluminum oxide substrate has been developed. The fabricated V₂O₅ membrane shows relatively higher selectivity to mono‐/divalent metal ions than trivalent metal ions, demonstrating that it favors rejecting the molecules with sizes larger than 0.95 nm. Remarkably, the ion permeability of V₂O₅ membrane is much superior to that of other well‐known two‐dimensional membranes owing to its large interlayer distance. These findings make it possible to construct nanoporous 2D membranes for gas separation and ion sieving.
