| 摘 要： | Tetragonal tungsten bronze K0.71Nd0.028WO3 was synthesized by rare earth co-permeation method using Keggin type POMs of α-K10[SiCu3(OH2)W9O37]·6H2O (abbreviated as SiW9Cu3) as precursor. XRD, XPS, XRF, TG-DTA were used to characterize the resulting material. The XPS results indicate that Nd has permeated and diffused into the body of the sample and exists in tungsten bronze in the form of K0.71Nd0.028WO3. The results of TG-DTA show that K0.71Nd0.028WO3 begins to decompose at 320 ℃. The consequence of DC four-probe shows that the conductivity of the sample permeated by rare earth is 103 times higher than that of the sample only permeated by methanol at room temperature. The conductivity of the sample only permeated by methanol is only 10-3 S·cm-1 but the conductivity of the sample permeated by rare earth is 1.65 S·cm-1.
