The Chromium doped Nickel ferrite nanopowders prepared by sol–gel combustion route by nitrates of respective metal ions. Formation of structure, morphology has been confirmed by X-ray powder diffraction method, FTIR and HRSEM. Additionally, electrical properties of prepared chromium doped nickel ferrites were studied using four probe method. The conductivity of the prepared ferrites was found to be decrease with increase in concentration of chromium. © 2016, Springer Science+Business Media New York.

Magnesium doped Ni ferrite nanoparticle (Ni1-xMgxFe2O4) has been synthesized by sol-gel combustion method and it has been analyzed using XRD, UV, FTIR and electrochemical charge-discharge studies. The observed XRD result confirms the nanostructure and it ranges from 23 to 28 nm. Furthermore, band gap energy values and functional group elements have been observed by UV and FTIR, respectively. The lattice constant values varies slightly with respect to magnesium concentration. The band gap energy values increase at the calcination temperature of 500 °C as 0.85, 1.15, 1.2, and 1.45 eV and it decreases when it was calcined at 900 °C as 1.3, 1.25, 1.15, 1.1 eV for x = 0.25, 0.5, 0.75, 1, respectively. The voltage profiles of Ni1-xMgxFe2O4 nanoparticle electrodes show the discharge and charge capacities of 1021 and 718 mAh/g at 500 °C and 1099 and 747 mAh/g at 900 °C, respectively. The high reversible capacities for the Mg doped Ni ferrite nanoparticle electrodes are confirmed as anode materials for Li ion batteries. © 2018 Elsevier B.V.

Impact of magnesium substitution in nickel ferrite: Optical and electrochemical studies

Known as a hard magnetic material, cobalt ferrite belongs to one of the most attractive classes of materials owing to its diverse technical applicability such as in catalysis, sensors, batteries. In this study, we synthesized Li- and Y-substituted cobalt ferrite nanoparticles using a sol–gel combustion method. Their mean crystallite sizes with spinel structures were calculated as 15–19 and 2–5 nm and their lattice constant values were 7.8 ± 0.02 and 8.5 ± 0.3 Å, respectively. The results also revealed that the band gap energy values of the prepared Li- and Y-doped cobalt ferrites decreased after doping compared with that of pure cobalt ferrite, and thus they appear to be promising for energy generation and storage applications. © 2018, Indian Association for the Cultivation of Science.
