Rapid synthesis of defective and composition-controlled metal chalcogenide nanosheets by supercritical hydrothermal processing.

This study presents a simple one-pot synthesis method to achieve few-layered and defective Mo(S,Se) 2 and (Mo,W)S 2 by using supercritical water with organic reducing agents from simple and less-toxic precursors. This synthesis process is expected to be suitable for preparing other various kinds of TMD solid solutions.
