Exsolution of Fe-based Pyramidal Nanostructures from a Noble Metal Doped Perovskite Matrix

Abstract

Homogeneous pyramidal oxide exsolution is demonstrated for the first time leveraging a La0.05Ag0.05Sr0.90FeO3 perovskite. The impressive structures were comprehensively characterised using XRD, SEM, TEM, XPS, DFT to reveal their structural and chemical identity. The hierarchical oxide formation highlights the potential of exsolution as a nano-engineering method for developing oxide-based catalysts.
