Realization of Wafer‐Scale 1T‐MoS₂ Film for Efficient Hydrogen Evolution Reaction

The octahedral structure of 2D molybdenum disulfide (1T‐MoS 2 ) has attracted attention as a high‐efficiency and low‐cost electrocatalyst for hydrogen production. However, the large‐scale synthesis of 1T‐MoS 2 films has not been realized because of higher formation energy compared to that of the trigonal prismatic phase (2H)‐MoS 2 . In this study, a uniform wafer‐scale synthesis of the metastable 1T‐MoS 2 film is performed by sulfidation of the...
