Direct synthesis of 1T-phase MoS2 nanosheets with abundant sulfur-vacancies through (CH3)4N+ cation-intercalation for the hydrogen evolution reaction

An efficient route based on in situ TMA cation ((CH₃)₄N⁺) intercalation is reported for direct synthesis of single-layer 1T-MoS₂ nanosheets with abundant sulfur vacancies for the hydrogen evolution reaction.
