摘　　要：以钒取代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新型钒取代多酸基硫化钼(PMoV-MoS2)复合材料.运用FT-IR、XRD、Raman等测试手段,对新型复合材料的结构和组成进行的分析测试结果表明,制得的复合材料中母体PMoV和MoS2的结构依然完整,且两者之间存在较强的化学键合作用.采用滴涂法将制得的复合材料涂至玻碳电极表面,对新材料进行循环伏安测试的结果表明,制得的复合材料显示出良好的导电性和电化学稳定性,具有显著的氧化还原特性.该研究为制备相关的电化学传感器提供了一种可行的材料和方法.A new polyacid-based molybdenum sulfide(PMoV-MoS2)composite was designed and synthesized by hydrothermal method using vanadium instead of polyoxometalates and graphene-like molybdenum sulfide as building elements.FT-IR,XRD and Raman were used to analyze and test the structure and composition of the new composite materials.The results show that the structure of the composite PMoV and MoS2 is still intact,and there is a strong chemical bond between the two.The prepared composite is coated on the surface of the glassy carbon electrode by the drop coating method.Cyclic voltammetry test results show that the prepared composite material performs good conductivity and electrochemical stability with significant redox characteristics,which provides a feasible material and research method for the preparation of related electrochemical sensors.
