Web1 feb. 2024 · LSCF underwent structural transformation under 5% H 2 /N 2 at 850 °C as demonstrated by the XRD spectra in Fig. 1 (a). The main XRD peaks of LSCF remained after 3 h of reduction (H 2 -Red-LSCF), while the additional peaks of bimetallic CoFe, La 2 FeO 4, and La 2 O 3 is observed. Web26 feb. 2024 · The narrow-scan XPS spectra of the LSCF electrodes pressed under different plates are shown in Fig. 8 a–c. The ratios of SrO, surface Sr, and bulk Sr are summarized in Fig. 8 d and e. It is confirmed that the type of contact materials would significantly affect the formation of SrO on the top surface of LSCF during long-term compression.
