Zirconium and Yttrium Co-Doped BaCo_0.8Zr_0.1Y_0.1O_3-δ: A New Mixed-Conducting Perovskite Oxide-Based Membrane for Efficient and Stable Oxygen Permeation.

ABSTRACT: Oxygen permeation membranes (OPMs) are regarded as promising technology for pure oxygen production. Among various materials for OPMs, perovskite oxides with mixed electron and oxygen-ion (e^-/O^2-) conducting capability have attracted particular interest because of the high O^2- conductivity and structural/compositional flexibility. However, BaCoO_3-δ-based perovskites as one of the most investigated OPMs suffer from low oxygen permeation rate and inferior structural stability in CO₂-containing atmospheres. Herein, zirconium and yttrium co-doped BaCoO_3-δ (BaCo_1-2xZr_xY_xO_3-δ, x = 0, 0.05, 0.1 and 0.15) are designed and developed for efficient and stable OPMs by stabilizing the crystal st
