采用固相反应法制备了 V_5O_(9+x)(x=0,1),它是一个多组元混合物,主结构属单斜晶系,晶胞参数随 x 而变化。室温电导率达10~0～10~(-2)(Ω·cm)~(-1)数量级,是纯电子电导化合物。用电化学法制备了 Cu_xV_5O_(9·1),室温电导率达10~(-1)(Ω·cm)~(-1)数量级,是电子和离子的混合导体。讨论了可能的结构和导电机理。
V_5O_ (9 + x) (x = 0,1) was prepared by the solid-state reaction method. It is a multi-component mixture. The main structure is monoclinic and the unit cell parameters vary with x. Room temperature conductivity of 10 ~ 0 ~ 10 ~ (-2) (Ω · cm) ~ (-1) on the order of magnitude, is pure electronically conductive compounds. Cu_xV_5O_ (9 · 1) was prepared by electrochemical method and its conductivity was about 10 -1 (Ω · cm -1) at room temperature. It is a mixed conductor of electrons and ions. The possible structures and conduction mechanisms are discussed.
