This work is dedicated to the study of properties perovskite ceramics based on lanthanum–strontium ferrite, and evaluation their resistance long-term thermal aging. As a method for obtaining ceramics, solid-phase mechanochemical grinding consequent annealing resulting mixtures was chosen. The novelty consists in assessment phase transformation dynamics ferrite-based relation temperature, alongs...

Perovskite cathodes have emerged as a promising alternative to traditional cathode materials in low-temperature solid oxide fuel cells (LT-SOFCs) due their exceptional catalytic properties and high oxygen reduction reaction (ORR) activity. Their fast activity chemical stability drawn significant attention lowering the operating temperature of SOFCs. In this study, Ba2+ Bi3+ are doped into LaFeO...

Perovskite-type oxides of LaFe(1+x)O(3+δ) (x = 0.0, 0.2, 0.5 and 0.7) were synthesized by citrate sol–gel methodto ensure the formation of nanosized perovskites. The physicochemical properties of these LaFe(1+x)O(3+δ)materials were characterized by thermal gravimetric/differential analyses, Fourier transform infraredspectroscopy, X-ray powder diffraction, scanning electron and...

A facile and environmentally friendly surface-ion adsorption method using CeCO₃OH@C as template was demonstrated to synthesize CeO₂-LaFeO₃ perovskite composite material. The obtained composite was characterized by X-ray diffraction (XRD), fourier transform infrared spectra (FT-IR), field-emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), thermo-gravimetric a...

In this work we have successfully fabricated nanocrystalline anatase TiO₂/perovskite-type porous nanosized LaFeO₃ (T/P-LFO) nanocomposites using a simple wet chemical method. It is clearly demonstrated by means of atmosphere-controlled steady-state surface photovoltage spectroscopy (SPS) responses, photoluminescence spectra, and fluorescence spectra related to the formed OH- radical amount that...
