| Popis: |
The Ln 1–x Ca x CoO 3–δ ( x = 0, 0.3, 0.4 and 0.5) (Ln = La, Er) phase formation process from chemical methods (amorphous and crystalline precursor decomposition) and a physical method (Pulsed Laser Deposition (PLD)) was monitored with high temperature X-ray powder diffraction (HT-XRD), thermal analysis, and high resolution transmission electron microscopy (HRTEM). The morphology and crystallographic structure of the products with identical composition obtained from different synthesis routes were systematically compared and evaluated for the possible application as electrocatalysts in bifunctional air electrodes. |
