Abstract

Nanocrystalline powders of Y₂Ru₂O₇ and Y_2-xPr_xRu₂O₇ were prepared by a co-precipitation method. Pr was chosen as the Asite dopant in order to increase the electrical conductivity of Y₂Ru₂O₇. Phase and morphology were studied by XRD and FE-SEM, which showed both systems exhibit a particle size of about 100 nm, and the doped powders were single pyrochlore phase. The electrical conductivity of a dense bar of Y_2-x Pr _xRu₂O₇ was measured at several temperatures by d.c. 4-probe method, while the electrochemical properties of Y_2-x Pr_xRu₂O₇ pyrochlores were tested in contact to ESB electrolytes, using Electrochemical Impedance Spectroscopy (EIS) in air. The Y_2-xPr_xRu₂O₇ on ESB electrolyte solid-state cells presents a significant decrease of electrodes impedance. copyright The Electrochemical Society.
