摘要
以多金属氧酸盐和类石墨烯结构硫化钼为构筑基元,采用水热法设计合成了新型多酸基硫化钼(POMs-MoS_2)复合材料SiMo_(12)-MoS_2.运用FT-IR、XRD、Raman和SEM等测试手段,对新材料的组成和结构进行表征和分析.结果表明,POMs与MoS_2两分子间存在很强的氢键键合作用,且母体多酸的骨架结构依然完整.以苯乙烯为底物,乙腈为溶剂,利用自制新材料催化苯乙烯环氧化反应,具有较高的催化活性和选择性.
Taking polyoxometalates and graphene-based molybdenum sulfide as the building blocks,a new Polyoxometallate Molybdenum Sulphide （POMs-MoS 2） composite of SiMo 12 -MoS 2 was designed by hydrothermal method.The composition and structure of the new material was characterized and analyzed by means of FT-IR,XRD,TG-DTA,UV-Vis and SEM.The results show that there is strong chemical interation between the two molecules of POMs and MoS 2,and the forming structure of the composite is still intact.With styrene as the substrate and acetonitrile as the solvent,the styrene epoxidation was catalyzed,showing high catalytic activity and selectivity.
