Abstract：Under the effect of ultrasonic waves, premonitory LixMoS2 was prepared by n-butyl lithium intercalating in the MoS2 layers, using the single-molecular-layer exfoliated-restacked technology. The value of x was in the range from 0.93 to 0.96 determined by atomic absorption spectrometry. Micro-structure and essential regularity of LixMoS2 were disclosed, for example octahedral configuration of LixMoS2 was metastable. It could provide experimental data for synthesizing new hydrogenation catalysts for interaction of MoS2 with high activity and selectivity. This work will lay the foundation for the research on hydrogenation catalysts and the production of high value-added MoS2.
