The solid solution of general formula Bi4V2−xSix/2Px/2O11−δ (0.0 ≤x≤ 0.5) has been synthesized and characterized by XRD, SEM, FTIR, ATD, Raman spectroscopy and Electrochemical Impedance Spectroscopy. The present study showed that compounds with x ≤ 0.3 are isostructural with the monoclinic α polymorph, while the compound with x = 0.4 is crystallize with the β polymorph. In the temperature range from 25 to 700 °C, the electrical conductivity of the substituted samples has been measured as a function of composition. In the low temperature range, the conductivity of the doped compounds is higher than that of the parent compound Bi4V2O11. The highest conductivity was obtained for x = 0.1.Read less <
