Optical, Magnetic and Gas Sensing Properties of LaFeO3 Nanoparticles Synthesized by Different Chemical Methods

Structural, magnetic, and dielectric properties of solution combustion synthesized LaFeO3, LaFe0.9Mn0.1O3, and LaMnO3 perovskites

“…2 Among perovskite oxides, La-based perovskites such as LaFeO 3 , 5,12-18 LaMnO 3 , [12][13][14][15] LaCrO 3 , 12 LaCoO 3 , 12,13,15 and LaNiO 3 , 15 etc. have been paid much attention because of their specific catalytic, 1,3,[12][13][14] photocatalytic, 4 electrocatalytic, 5,15,19 magnetic, [16][17][18][19] electrical, 16,19 optical, [17][18][19] and sensing 17 properties. It has been well-documented that these properties strongly depend on various characteristics like the degree of crystallinity, phase purity, particle size, and particle shape.…”

“…Modification by doping of requisite metal ions with +2 and +3 oxidation states into the lattice also has an impact on their properties. In this regard, it must be mentioned that different parameters such as preparation method, 17 thermal treatment, 17,20,21 crystallite size, 18 morphology, 21 nature of doped cation, [12][13][14][15][16]22 and dopant concentration, 16,22 etc. have a significant impact on the magnetic [16][17][18][20][21][22][23][24][25] and dielectric 21 properties of LaFeO 3 -based materials.…”

Heterostructured thin LaFeO3/g-C3N4 films for efficient photoelectrochemical hydrogen evolution

“…Most water splitting studies were conducted using wide bandgap semiconductors like TiO 2 or ZnO that can only be activated by UV light [11,12]. In recent years, intensive efforts were devoted to the extension of TiO 2 or ZnO visible light absorption and to the improvement of their photocatalytic properties via doping or building heterostructured catalysts in which the separation of charge carriers is improved [13][14][15] Recently, lanthanum ferrite perovskite (LaFeO 3 ) has attracted a great attention [16][17][18][19][20][21], with applications in sensors [22], catalysts [23] and monitoring [24] due to its good chemical and thermal stability and its low toxicity. Moreover, LaFeO 3 has an advantageous optical bandgap, up to 2.1 eV, allowing the absorption of visible light until 590 nm.…”

Lanthanum Ferrite Ceramic Powders: Synthesis, Characterization and Electrochemical Detection Application

“…Perovskite-type oxides have received growing attention due to its diversity and performance [1][2][3][4][5]. Among the perovskite materials, lanthanum ferrite has been investigated intensively due to its potential applications in biosensors [6], (photo)catalysis [7], chemical sensors [8,9], electrochemistry field [10][11][12][13][14][15], magnetic, optical, and ferroelectric properties [16,17], environmentally-friendly pigments [18], spin electronic devices [19,20], and more.…”
