Structural and Electrical Properties of Ca2+ Doped LaFeO3: The Effect of A-site Cation Size Mismatch
Abstract Perovskite nanoparticles La 1-x ? x Fe 1-y y O 3 , ( = 0.0, 0.01 and 0.02) were prepared using the citrate combustion method. The samples crystallized in a single phase orthorhombic structure. energy dispersive spectroscopy (EDS) confirms that chemical composition is very close to nominal one. particle size values indicated nano scale. selected area electron diffraction (SAED) pattern ...
The microstructure of multiferroic LaFeO₃-YMnO₃ (LFO-YMO) multilayers grown on (001)- and (111)-SrTiO₃ substrates is characterized by the transmission electron microscopy (TEM). Detailed TEM characterization reveals that LFO-YMO multilayers grown on both substrates have clear layer-by-layer morphology and distinct chemical-composition layered structure. The most notable feature is that LFO-YMO ...
Solar photocatalytic inactivation (SPCI) of E. coli as the indicator microorganism using LaFeO3 (LF) has already been investigated under various experimental conditions, excluding any role natural organic matter (NOM). However, comprehensive information about behavior and its mechanism in presence NOM, well NOM components via solar photocatalysis LF a photocatalyst, prime importance understandi...
In this work, two types of solvents ethanol or water were used in preparation of the LaFeO3 catalysts by citrate sol gel method. The obtained samples were subjected to various calcination temperatures in order to study the catalytic activity and stability for methanol electro-oxidation by XRD, cyclic voltammetry and chronoamperometry. The crystallinity of the LaFeO3 ph...
Abstract In this study, LaFeO 3 perovskite is synthesized by the flash method, and then a simple method developed for growing SiO 2 on its surface to construct core/shell nanocomposite. The thickness of shell controlled varying amount tetra-ethyl orthosilicate (TEOS). Two @SiO samples with thicknesses were synthesized. Herein, lattice parameters, morphology, magnetic, adsorption properties inve...
