The perovskite Lanthanum Strontium Cobalt Ferrite (LSCF) is investigated as the cathode material used in intermediate-temperature solid oxide fuel cells (IT-SOFCs). In the present study, La0.6−xDyxSr0.4Co0.2Fe0.8O3−δ (x = 0, 0.3, 0.6) was synthesized through the coprecipitation method. The obtained precipitate was calcined at 500, 700, 900, and 1000°С. Phase characterization of the synthesized LSCF and LDySCF powder before and after heat treatment at 700°С was carried out by X-ray diffraction (XRD) analysis. XRD patterns revealed that the perovskite phase was obtained at 700°С in all calcined samples. Chemical bond study to investigate the synthesis process was conducted using the Fourier transform infrared spectroscopy technique. Thermal analysis of DTA and TG has been utilized to investigate how the calcination temperature affects the perovskite phase formation. According to the STA results, the perovskite phase formation started at 551°С and completed at 700°С. The density values of synthesized powders were 6.10, 6.11, and 6.37 g·cm−3for the undoped and doped samples calcined at 700°С. Powder morphology was studied by field emission scanning electron microscopy (FE-SEM). The micrographs showed the spherical-shaped particles with the average particle size of 24–131 nm.

“…In the preliminary stage of the investigation, the model reaction of isatin, dimedone, and cytosine (Scheme 2) was carried out by using various amounts of La 2 O 3 NPs [ 36 ] and (MWCNTs)‐COOH/La 2 O 3 in various solvents and solvent‐free conditions. As shown in Table 1, the best catalyst was (MWCNTs)‐COOH/La 2 O 3 (5 mol%).…”

Spiro‐acridine/indoline and indoline derivatives were synthesized by the three‐component reaction of isatin, dimedone, and amines or amino acids in the presence of acid‐functionalized multiwalled carbon nanotubes/La2O3 (MWCNTs)‐COOH/La2O3 hybrid (5 mol%) as a highly efficient catalyst in ethanol. The assigned structure was further established by CHN analysis, NMR, and FTIR spectra. (MWCNTs)‐COOH/La2O3 was fabricated by the reaction of functionalized (MWCNTs)‐COOH and La(NO3)3.6H2O in acetic acid. Synthesis of La2O3 nanoparticles and their conjugation on the surface of MWCNT have been confirmed by FTIR, scanning electron microscopy, transmission electron microscopy, X‐ray diffraction, and energy‐dispersive X‐ray spectroscopy.

“…After modifying the pure CS with La2O3, one absorption peak attributed to La-O bond appeared at nearly 645 cm -1 . Consequently, the presence of the above-stated bands recognizes the existence of La2O3 [36]. The sharpness and area of SiO4 group shrinkage with the addition of La2O3 which could be ascribed to the difference of electronegativity and polarizing power between La 3+ and Ca 2+ [37].…”

Bioactive calcium silicate (CS) and lanthanum oxide (La2O3) doped bioactive calcium silicate (La-CS) materials were successfully prepared in this study. CaO, SiO2, and La2O3 used as precursors materials followed by the solid-state reaction at 1050°C for 2h. The retained particles were crushed and characterized using various methods such as XRD, FTIR, and SEM. Based on the XRD analysis outcomes, two phases of calcium silicate (CaSiO3 and Ca2SiO4) were obtained, and the quantity of CaSiO3 phase increased gradually with increasing La2O3 amount. Based on the FTIR analysis outcomes, the sharpness and area of SiO4 group shrinkage with the addition of La2O3. Based on the SEM analysis outcomes, calcium silicate particles appeared as spheroids like particles and transformed to elongated spheroidal particles with the addition of 20 wt.% of La2O3. Furthermore, incorporating 20 wt.% of La2O3 reduced the size of calcium silicate particle up to 60% of the pure samples.
