Anderson结构钼系过渡金属稀土盐的电化学性质研究

Electrochemical characterization for the rare earth salt of molybdenum series transition metals with Anderson structure

目的对具有Anderson结构的稀土元素钼系化合物进行电化学表征。方法采用电化学工作站三电极体系。结果首先合成了母核Na3[CrMo6O24H6]·8H2O,分别采用玻碳电极和制备的碳糊电极进行电化学表征。其次分别制备了Ce[CrMo6O24H6]、Sm[CrMo6O24H6]、Eu[CrMo6O24H6]的碳糊电极,测定了它们的循环伏安图。结论从循环伏安图中看出,使用两种电极时Na3[CrMo6O24H6]的氧化还原行为相似,均是单电子的一步不可逆还原。三种化合物的氧化还原行为与母核相似,说明这三种化合物均经历单电子的一步不可逆还原过程。

Objective To make an electrochemical characterization for rare-earth elements molybdenum compounds of the Anderson type.Methods Three-microelectrode-system of electrochemical workstation was employed.Results The parent nucleus(Na3[CrMo6O24H6]·8H2O) were synthesized firstly and made the electrochemical characterization by glassy carbon electrode and carbon paste electrod.Secondly,carbon paste electrod of Ce[CrMo6O24H6],Sm[CrMo6O24H6],Eu[CrMo6O24H6]were prepared and their cyclic voltammetry chart were measured.Conclusion From cyclic voltammetry chart,the parent nucleus' s redox behavior were similar by using two electrodes,which were all single-electron step irreversible reduction.Three compounds' s redox behavior were similar to parent nucleus,which indicated they all have experienced single-electron step irreversible reduction.
