Strained oxide materials, Catalysts, Oxygen reduction reactions, Oxygen ion transport, Thin-film deposition
Electrochemical energy conversion devices, such as fuel cells, catalytic reaction chambers, and membranes for oxygen gas separation in oxyfuel combustion systems
Limited surface exchange efficiency of traditional bulk oxide materials
This invention introduces strained oxide materials that include epitaxial thin-film deposition, core-shell particle synthesis and thermal and/or chemical induced strain of epitaxial thin-film or core-shell particles. The strain is induced by the lattice mismatch between the shell and core materials, and by the curvature of the core particle and conformal coating of the shell. The procedure for preparing the substrate and deposing the thin-films is provided.
