Summary: The effect of organic sulfur sources on the formed MoS2 phase is investigated, and it is found that the decomposition temperature of the sulfur precursors is crucial in determining the type of MoS2 formed. Sulfur precursors with lower decomposition temperatures lead to the formation of metallic MoS2, while higher decomposition temperatures result in semiconducting MoS2. Metallic-phase MoS2 exhibits great electrocatalytic hydrogen evolution reaction (HER) performance in acidic conditions. However, the controllable synthesis of metallic-phase MoS2 remains challenging due to the unclear key factor determining the phase types.
