Exfoliation of large-flake, few-layer MoS2 nanosheets mediated by carbon nanotubes

Abstract

A facile and scalable exfoliation approach is developed to prepare large-flake, few-layer MoS₂ nanosheets with the assistance of carbon nanotubes (CNTs). CNTs not only facilaite the efficient exfoliation of MoS₂ nanosheets, but also benefit their subsequent electrochemical applications for both hydrogen evolution and sodium-ion storage. This CNT-mediated exfoliation approach can be extended to other kinds of 2D materials.
