Two-dimensional (2D) transition metal dichalcogenides (TMDCs) with a unique
unity of favorable electronic and mechanical properties have been developed for fundamental studies and applications in electronics, spintronics, optoelectronics, energy harvesting and
catalysis. However, as they are unstable under harsh conditions, and prone to degradation in
the ambient environment, most TMDCs applications are limited. In this review, we analyze
the recent advances in the research of environmental stability in TMDCs, covering the latest
growth methods, the fundamental mechanisms for stability and kinds of routes to protect 2D
TMDCs materials from aging and deterioration. By analyzing key factors that affect TMDCs
stability from the growth process, we present a short review of optimizing growth methods for
improving the stability of TMDCs. Finally, by providing insights into existing factors, this
review is expected to guide the growth of stable TMDCs, which could lead to a new potential
approach to growing advanced materials and designing more unexplored heterostructures.
