Cobalt-doped praseodymium nickelate PrNi1−xCoxO3−δ (PNCx) and Y-doped ceria Ce0.9Y0.1O2−δ (YDC) oxides were synthesized via Pechini route. PNCx+YDC composites were prepared via ultrasonic dispersion of the mixture of perovskite and fluorite nanopowders in isopropanol with addition of polyvinyl butyral followed by drying, pressing and sintering at 1300°C. The oxygen mobility and reactivity of powdered...
This paper presents the results of research aimed at design of multilayer asymmetric oxygen separation membranes comprised of functionally graded by composition and porosity nanocomposite layers with mixed ionic–electronic conductivity (MIEC) and a high oxygen mobility supported on the compressed Ni–Al alloy foam substrate. Complex oxides with fluorite-like structure (Ce 0.9 Gd 0.1 ...
