Molybdenum Disulfide: Lithium Intercalation Compound Dramatically Influences the Electrochemical Properties of Exfoliated MoS 2 (Small 5/2015)

Exfoliation of layered structures such as MoS 2 (exemplified here by layered structure of Antelope Canyon, USA) strongly depends on the intercalator used. As found by M. Pumera and co‐workers on page 605, n ‐Bu‐Li and t ‐Bu‐Li produce a more efficient exfoliation of MoS 2 than Me‐Li. Exfoliation with n ‐Bu‐Li and t ‐Bu‐Li gives rise to MoS 2 sheets more catalytic for the hydrogen evolution reaction than those obtained with Me‐Li. Similar results are obtained testing their capacitive behavior, which is distinctively larger for MoS 2 exfoliated with n ‐Bu‐Li and t ‐Bu‐Li than MoS 2 exfoliated with Me‐Li.
