An Effective Method for the Fabrication of Few‐Layer‐Thick Inorganic Nanosheets

Intercalation and exfoliation of lithium: Few-layer-thick inorganic nanosheets (BN, NbSe(2), WSe(2), Sb(2)Se(3), and Bi(2)Te(3)) have been prepared from their layered bulk precursors by using a controllable electrochemical lithium intercalation process. The lithium intercalation conditions, such as cut-off voltage and discharge current, have been systematically studied and optimized to produce high-quality BN and NbSe(2) nanosheets.
