Hydrothermal fabrication of hyacinth flower-like WS2 nanorods and their photocatalytic properties

Hyacinth flower-like WS2 nanorods were successfully synthesized via a facile hydrothermal method. Sodium tungstate and L-cysteine were employed as source materials. The final products were characterized by XRD, XPS, EDS, SEM and TEM. A possible formation mechanism of these novel WS2 nanorods has been proposed. In addition, the photocatalytic activity of WS2 nanorods toward the rhodamine B was also investigated.
