Abstract

•The nanocrystalline LSCF perovskite was prepared by ultrasound assisted synthesis.•XRD analysis showed the presence of LSCF and the formation of CoFe2O4.•The TEM micrographs confirmed the uniform equiaxial shaped nanopowders.

La0.6Sr0.4Co0.2Fe0.8O3 − δ (LSCF) perovskite nanostructures were synthesised using a 42 kHz ultrasound assisted synthesis technique for the fabrication of electrodes in the intermediate and/or low temperature solid oxide fuel and electrolysis cells (SOFCs/SOECs). The obtained nanomaterials were dried at 110 °C followed by calcination in a normal atmosphere at various temperatures from 400 to 1000 °C for 2 h. Powder characteristics such as crystal structure, thermal decomposition, particle size and morphology were analysed. The transmission electron microscopy (TEM) study revealed the uniform equi-axial shape and growth of the obtained nanostructures with respect to the calcination temperature till 800 °C. The structural and chemical analyses confirmed the existence of LSCF and CoFe2O4 phases.
