Abstract

Previously unreported Ce_0.9Pr_0.1O_2-δ-Pr_0.6Ca_0.4MnO_3-δ (CPO-PCMO) dual-phase membrane is designed and successfully fabricated. The crystal structure, surface morphology, stability, and oxygen permeability is systematically investigated. The XRD results reveal that CPO-PCMO dual-phase membranes are made up of cubic fluorite phase and orthorhombic perovskite phase, which exhibit excellent stability at elevated temperature under air atmospheres as well as various low oxygen conditions such as Ar or CO₂ atmospheres. In addition, no obvious holes, cracks, and impurities are observed. The obtained CPO-PCMO membrane with 0.8 mm thickness exhibits comparable oxygen permeability with a flux of 0.23 mL min⁻¹cm⁻² under air/He gradient at 1000 °C and stably works over 300 min without obvious deterioration under air/CO₂ gradient, suggesting it has good CO₂ stability.
