Abstract

Ultrathin 2D nanostructures have shown many unique properties and are attractive for various potential applications. Here, we demonstrated a strategy to synthesize ultrathin VO_x nanosheets. The as-obtained ultrathin VO_x nanosheets showed a large Brunauer-Emmett-Teller (BET) surface area of 136.3 m²g^-1, which is much larger than that of 1D multilayer VO_x nanotubes. As a proof of concept, these hydrophilic ultrathin nanosheets were applied in water treatment and exhibited excellent absorption capability to remove Rhodamine B (RhB) in wastewater owing to their large specific surface area, good hydrophilic property, and more negative zeta potential. In addition, this method could be generalized to prepare other 2D nanostructures with great potential for various attractive applications.
