Abstract
Vn+ doped NiFe2O4, Ni1-xVxFe2O4 (where x = 0.1, 0.3, and 0.5) nanomaterials were synthesized by sol-gel and freeze drying method simultaneously using nitrates of iron, and nickel, and ammonium vanadate as the starting materials. Powder X-ray Difraction (XRD) showed that all composition was found to have cubic spinel, hexagonal and monoclinic structure. The average crystallite size using scherrer calculation was found to be in the range of 20 - 42 nm. The band gap energy (Eg) of undoped NiFe2O4 was estimated to be 1.9 eV from UV-Vis diffuse reflectance spectroscopy (DRS). With the increase of Vn+ dopant, the Eg value both decreased and increased from 1.6 eV to 2.0 eV, due to the difference of particle size of the samples.
