Homogeneous pyramidal oxide exsolution is demonstrated for the first time leveraging a LaAgSrFeO 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.
首次利用LaAgSrFeO钙钛矿证明了均匀的金字塔形氧化物析出。使用XRD、SEM、TEM、XPS和DFT对这些令人印象深刻的结构进行了全面表征，以揭示它们的结构和化学特性。分层氧化物的形成突出了析出作为一种用于开发氧化物基催化剂的纳米工程方法的潜力。
