The metallic 1 T phase of MoS 2 has been widely identified to be responsible for the improved performances of MoS 2 in applications including hydrogen evolution reactions and electrochemical supercapacitors. To this aim, various synthetic methods have been reported to obtain 1 T phase‐rich MoS 2 . Here, the aim is to evaluate the efficiencies of the bottom‐up (hydrothermal reaction) and top‐down (chemical exfoliation) approaches in producing 1 T phase MoS 2 . It is established in this study that the 1 T phase MoS 2 produced through the bottom‐up approach contains a high proportion of 1 T phase and demonstrates excellent electrochemical and electrical properties. Its performance in the hydrogen evolution reaction and electrochemical supercapacitors also surpassed that of 1 T phase MoS 2 produced through a top‐down approach.
