Exsolution of Fe-based pyramidal nanostructures from a noble metal doped perovskite matrix
Homogeneous pyramidal oxide exsolution is demonstrated for the first time leveraging a La<sub>0.05</sub>Ag<sub>0.05</sub>Sr<sub>0.90</sub>FeO<sub>3</sub> perovskite. The impressive structures were comprehensively characterised using XRD, SEM, TEM, XPS, and 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.
