Photochemically engineered ultra-stable 1T MoS 2 by flow synthesis

摘要: A novel synthesis method for stable conversion of 2H to 1T MoS2 is developed by photoirradiation of ammonium intercalated 2H-MoS2. The synthesized 1T phase in the final product showed excellent long-term stability, and orders of magnitude improvement in electrical conductivity. The denser active sites in the synthesized material contributed to an enhanced HER activity. The methodology can be translated to a continuous flow process paving the way for the large-scale production of 1T MoS2.
