Superior Adsorption and Regenerable Dye Adsorbent Based on Flower-Like Molybdenum Disulfide Nanostructure

Herein we report superior dye-adsorption performance for flower-like nanostructure composed of two dimensional (2D) MoS(2) nanosheets by a facile hydrothermal method, more prominent adsorption of cationic dye compared with anodic dye indicates the dye adsorption performance strongly depends on surfa...

description Herein we report superior dye-adsorption performance for flower-like nanostructure composed of two dimensional (2D) MoS(2) nanosheets by a facile hydrothermal method, more prominent adsorption of cationic dye compared with anodic dye indicates the dye adsorption performance strongly depends on surface charge of MoS(2) nanosheets. The adsorption mechanism of dye is analyzed, the kinetic data of dye adsorption fit well with the pseudo-second-order model, meanwhile adsorption capability at different equilibrium concentrations follows Langmuir model, indicating the favorability and feasibility of dye adsorption. The regenerable property for MoS(2) with full adsorption of dye molecules by using alkaline solution were demonstrated, showing the feasibility of reuse for the MoS(2), which is promising in its practical water treatment application.
