AbstractThe metallic 1 T phase of MoS2 has been widely identified to be responsible for the improved performances of MoS2 in applications including hydrogen evolution reactions and electrochemical supercapacitors. To this aim, various synthetic methods have been reported to obtain 1 T phase‐rich MoS2. 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 MoS2. It is established in this study that the 1 T phase MoS2 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 MoS2 produced through a top‐down approach.
