Tuning the properties of MoS layers for electrocatalytic applications can be achieved by reducing thickness, creating edges, and introducing S-vacancies, utilizing a unique salt-assisted chemical vapor deposition (CVD) method to grow ultrathin nanocrystals.*
-
Advanced microscopy techniques reveal that the unique morphology of these MoS layers leads to distinct features in their Raman and photoluminescence spectra, and the S-vacancy levels can be adjusted during CVD growth using specific gas mixtures.*
-
Electrochemical testing shows that the MoS layers perform well as cathodes with high Faradaic efficiencies and stability in acidic conditions, and an optimal concentration of S-vacancies significantly enhances their electrochemical
