The crystalline phase of layered transition metal dichalcogenides (TMDs) directly determines their material property. The most thermodynamically stable phase structures in TMDs are the semiconducting 2H and metastable metallic 1T phases. To overcome the low phase purity and instability of 1T‐TMDs, which limits the utilization of their intrinsic properties, various synthesis strategies for 1T‐TMDs have been proposed in phase‐engineering studies. Herein, a facile and scalable synthesis of 1T…
