A mini-review on AFe2O4 (A = Zn, Mg, Mn, Co, Cu, and Ni) nanoparticles: Photocatalytic, magnetic hyperthermia and cytotoxicity study

Lanthanum ferrite nanofibers were electrospun from a chemical sol and calcined at 600 °C to obtain single-phase LaFeO3 (LFO) perovskite. High-resolution transmission electron microscopy in conjunction with 3D tomographic analysis confirmed an interwoven network of hollow and porous (surface) LFO nanofibers. Owing to their high surface area and p-type behavior, the nanofiber meshes showed high chemoselectivity toward reducing toxic gases (SO2, H2S) that could be reproducibly detected at very low concentrations (<1 ppm), well below the threshold values for occupational safety and health. An increased sensitivity was observed in the temperature range of 150–300 °C with maximum sensor response at 250 °C. The surface reaction at the heterogeneous solid (LFO)/gas (SO2) interface that confirmed the formation of La2(SO4)3 was investigated by X-ray photoelectron spectroscopy. Moreover, the LFO fibers showed a high selectivity in the detection of oxidizing and reducing gases. Whereas superior detection of NH3 and H...

LaFeO3 Nanofibers for High Detection of Sulfur-Containing Gases

Roles of oxygen vacancies and pH induced size changes on photo- and radioluminescence of undoped and Eu3+-doped La2Zr2O7 nanoparticles

Single phase rare earth pyrochlores, Ln2M2O7, were produced as nanofibers and thin films by electrospinning and spin-coating of chemical sols obtained from bimetallic metal–organic precursors, LnIIIMII(OtBu)5Py (LnIII = La, Pr, Nd, Sm, Er, Yb; MII = Ge, Sn, Pb; Py = pyridine). Compatibility of the metal ratio in the single-source compounds was confirmed by single crystal X-ray diffraction analyses and the ratio was preserved during the processing as the crystalline pyrochlore materials originated from an amorphous preceramic aggregate as confirmed by powder XRD and TEM studies. The photocatalytic activity of the Nd2Sn2O7 nanofibers was found to be significantly higher than that of TiO2. Nd2Sn2O7 thin films deposited on F:SnO2 as bilayered Nd2Sn2O7//Fe2O3 photoanodes showed superior photoelectrochemical (PEC) efficiency for water splitting reaction with an over 3-fold higher photocurrent density than bare Fe2O3 photoanodes.

Precursor-Derived Rare Earth Metal Pyrochlores: Nd2Sn2O7 Nanofibers and Thin Films As Efficient Photoabsorbers

This study presents a modification of structure-dependent elastic, thermodynamic, magnetic, transport and magneto-dielectric properties of a Ni–Zn–Co ferrite tailored by Gd3+ substitution at the B-site replacing Fe3+ ions. The synthesized composition of Ni0.7Zn0.2Co0.1Fe2−xGdxO4 (0 ≤ x ≤ 0.12) crystallized with a single-phase cubic spinel structure that belongs to the Fd3̄m space group. The average particle size decreases due to Gd3+ substitution at Fe3+. Raman and IR spectroscopy studies illustrate phase purity, lattice dynamics with cation disorders and thermodynamic conditions inside the studied samples at room temperature (RT = 300 K). Ferromagnetic to paramagnetic phase transition was observed in all samples where Curie temperature (TC) decreases from 731 to 711 K for Gd3+ substitution in Ni–Zn–Co ferrite. In addition, Gd3+ substitution reinforces to decrease the A-B exchange interaction. Temperature-dependent DC electrical resistivity (ρDC) and temperature coefficient of resistance (TCR) have been surveyed with the variation of the grain size. The frequency-dependent dielectric properties and electric modulus at RT for all samples were observed from 20 Hz to 100 MHz and the conduction relaxation processes were found to spread over an extensive range of frequencies with the increase in the amount of Gd3+ in the Ni–Zn–Co ferrite. The RLC behavior separates the zone of frequencies ranging from resistive to capacitive regions in all the studied samples. Finally, the matching impedance (Z/η0) for all samples was evaluated over an extensive range of frequencies for the possible miniaturizing application.
