Abstract

Through a facile and effective strategy by employing lithium molten salts the controlled synthesis of 2H- and 1T-MoS₂ monolayers with high-yield production is achieved. Both phases of MoS₂ monolayers exhibit high stabilities. When used as a catalyst for hydrogen evolution, these phased MoS₂ monolayers deliver respective advantages in the field of electro- and photo-catalytic hydrogen evolution.
