摘要：

A ternary heteropoly acid (HPA) H6SiW10V2O40 center dot 14H(2)O was prepared and investigated in this paper. The structure feature and hydration of this HPA was characterized by IR, XRD, UV, and TG-DTA. This HPA exhibits a high proton conductivity, which is 7.4 x 10(-3) S.cm(-1) at 25 degrees C and 70% relative humidity. It is a novel high proton conductor. The conductivity increases with higher temperature, and it exhibits Arrhenius behavior, with the activation energy value of 21.02 kJ.mol(-1) for proton conduction, indicating the proton conduction mechanism is dominated by vehicle mechanism.
