This study presents a simple one-pot synthesis method to achieve few-layered and defective Mo(S,Se)2 and (Mo,W)S2 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.

Briefly describe the importance of this publication: 
This paper reports a new synthetic method for exfoliation of two dimensional transition metal dichalcogenides using supercritical fluids.
