摘　　要：首先在超声波作用下,采用单分子层剥离-重堆技术,正丁基锂柱插MoS2夹层,合成了前驱体LixMoS2和La/Ni-MoS2复合材料,以环丁烯砜催化加氢为探针反应,考察了其催化活性。环丁烯砜催化加氢制备环丁砜最佳反应条件:n(La)、n(Ni)的配比R=0.05;氢气压力2.5MPa;反应温度60℃,环丁烯砜的转化率为9.8%,环丁砜的收率达到了95.5%,为工业装置的技术改造提供了较好的实验依据。Effect of ultrasonic waves, premonitory Li2MoS2 and La/Ni-MoS2 composite were prepared by n-butyl lithium intercalating in the MoS2 layers, using the single-molecular-layer exfoliated-restacked technology. The effect of catalyst on the performance was investigated with catalytic hydrogenation of sulfolene over La/Ni-MoS2 composite as probe reaction. The catalyst evaluation results show that the optimum atomic ratio, hydrogen pressure and reactive temperature are n（La）/n（Ni）=0.05, 2.5MPa and 60℃, respectively. Under such condition, conversion of sulfolene was 99.8%, the yield of sulfolane reached 95.5%. This study could provide experimental data for the technical reform of industry equipment.
