摘要：

The vanadotungstogermanic heteropoly acid H5GeW11VO40. 22H(2)O has been prepared for the first time by the stepwise acidification and the stepwise addition of solutions of the component elements. The suitable condition for the synthesis reaction is given. The product was characterized by means of ICP, potentiometric titration, IR, UV, V-51 NMR, X-ray powder diffraction and thermal analysis. The result of AC impedance measurement shows that its proton conductivity is 2.43 x 10(-3) S cm(-1) at 18 degreesC. (C) 2000 Elsevier Science B.V. All rights reserved.
