Abstract

An efficient nitrate/HCl chemical exfoliation system for rapid production of MoS₂and WS₂nanosheets were presented here. After exfoliation in the NaNO₃/HCl solution with the assistant of ultrasonication, MoS₂and WS₂nanosheets were produced with yields of 58% and 52%, respectively. The morphologies and crystallinity of MoS₂and WS₂nanosheets were characterized by transmission electron microscopy, atomic force microscopy and X-ray diffraction spectroscopy. This efficient exfoliation method is based on the synergy effects of surface etching, insertion of ions and eruption of gas bubbles. The MoS₂and WS₂nanosheets exhibited improved catalytic activity toward the oxygen-reduction reaction.
