Phase-selective Hydrothermal Synthesis of Metallic MoS2 at High Temperature

The metallic 1T crystal phase of MoS2 is beneficial for energy applications but its synthesis remains challenging. Here, we report an improved hydrothermal synthesis procedure using the chelating interaction of l-cysteine and MoO3 to increase the 1T phase purity at elevated temperature. The obtained...

Zusammenfassung:The metallic 1T crystal phase of MoS2 is beneficial for energy applications but its synthesis remains challenging. Here, we report an improved hydrothermal synthesis procedure using the chelating interaction of l-cysteine and MoO3 to increase the 1T phase purity at elevated temperature. The obtained material exhibits excellent activity and stability towards the hydrogen evolution reaction.
