中文摘要：

在超声波作用下，采用单分子层剥离-重堆技术，利用正丁基锂对MoS2夹层进行剥离，合成了前驱体LixMoS2。通过原子吸收光谱得到x=0．93～0．96；XRD、FTIR、UV—Vis的检测揭示了LixMoS2的微观结构和内在规律性，证实了LixMoS2为亚稳态的八面体构型。研究结果为进一步合成高活性、高选择性的柱撑MoS2加氢催化剂提供了实验依据，同时为加氢催化剂的研究及生产高附加值的二硫化钼奠定了基础。

英文摘要：

Under the effect of ultrasonic waves, premonitory LixMoS2 was prepared by n-butyl lithium intercalating in the MoSe layers, using the single-molecular-layer exfoliated-restaeked 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 Li, MoS2 were disclosed, for example octahedral configuration of LixMoS2 was metastabte. 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.
