Electro-trapping uranium with a cost-effective and scalable ice-templated MXene/VMT electrode

Abstract

Here, we present a breakthrough in fabricating 3D porous MXene/VMT (3D-TV) electrodes via a facile ice-templating route. This strategy not only effectively mitigates nanosheet restacking but also eliminates the need for costly additives and complex processing. The resulting electrode shows an impressive uranium adsorption capacity of 1852 mg g⁻¹ at −5 V, demonstrating a novel and scalable pathway for electrochemical uranium recovery.
