Molybdenum Disulfide: Lithium Intercalation Compound Dramatically Influences the Electrochemical Properties of Exfoliated MoS₂ (Small 5/2015)

Exfoliation of layered structures such as MoS2 (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 MoS2 than Me-Li. Exfoliation with n-Bu-Li and t-Bu-Li gives rise to MoS2 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 MoS2 exfoliated with n-Bu-Li and t-Bu-Li than MoS2 exfoliated with Me-Li.
