Research Abstract

Chemical exfoliation of MoS2 and WS2 by using lithium intercalation has been investigated to make atomic-layer materials for efficient mass production. The structural analysis for exfoliated materials was performed by transmission electron microscope, and the coherent interface of metallic phase (1T) and semiconducting phase (2H) was clarified. In the WS2 atomic-layer sample, the metallic superlattice phase (1T') showing the mazing lattice patterns was found. The exfoliated WS2 and MoS2 atomic-layer samples have high catalytic capability of hydrogen evolution reaction, compatible to that of Pt. This high catalytic activity comes from the conducting metallic phase (1T) and the active sites from local strain induced by the superlattice.
