Synthesis, Characterization, Magnetic and Photocatalytic properties of Bi, Co and Mn Co-doped Neodymium Ferrite (Nd0.5Bi0.2(Co0.2Mn0.1)FeO(3-δ)) Solid Solution

Ibrahim A.*, Bice S. Martincigh, Sreekantha B. Jonnalagadda

Bismuth and cobalt co-doped perovskite-type nanomaterials with the composition Nd0.5Bi0.2(Co0.3Mn0.1)FeO3-δ were syn thesized by using the citric acid sol-gel route and annealed at annealing temperatures (TA) of 400, 750 and 900°C to pro duce powders labelled NdCo400, NdCo750 and NdCo900 respectively.  The powders obtained were characterized using ...

Effect of annealing conditions on the magnetic, optical and photocatalytic properties of the perovskite-type material La1-x(Bix)FeO3-δ

Ibrahim A.*, Bice S. Martincigh, Sreekantha B. Jonnalagadda

Novel perovskite-type nanomaterials with the composition La1-x(Bix)FeO3-δ (where x = 0.5 and 0.2) were synthesized by using a modified citric acid sol-gel route and annealed at 900 °C in (1) in air (LB0.5FO-air and LB0.2FO-air), and (2) in Argon atmosphere (LB0.5FO-Ar and LB0.2FO-Ar). Scanning electron microscopy and powder X-ray diffraction ana...

Characterization of hematite nanoparticles synthesized via sol gel method in tween 20 surfactant solution

IBRAHIM ABDULKADIR*, Bice S. Martincigh

Samples of hematite (α-Fe2O3) nanoparticles (HTW) have been synthesized through a modified sol-gel method in Tween 20 (a polysorbate surfactant), separate portions of the powders were annealed at three different temperatures (400, 500 and 600 °C). The samples were characterized by X-ray diffraction (XRD), high-resolution electron microscopy (HRTE...
