Abstract
Spinel MnxZn1−xFe2O4 (0.0 ≤x≤ 1.0) nanocatalysts were successfully prepared by simple one-pot microwave combustion method using glycine as the fuel. X-ray powder diffraction (XRD), energy-dispersive X-ray (EDX) analysis, and Fourier transform infrared (FT-IR) spectral results confirmed the formation of pure-phase cubic spinel structured products. Average crystallite sizes of the samples were calculated using Sherrer’s formula, and the range from 21.15 to 15.48 nm. Spherical-shaped particles like nanostructured morphology were confirmed by high-resolution scanning electron microscopy (HR-SEM) and transmission electron microscopy (HR-TEM) analyses. Magnetic characterization of the samples was measured by vibrating sample magnetometer (VSM), and it was observed that the magnetization values increased with increasing Mn 2+ cation, due to the replacement of the non-magnetic nature of Zn 2+ by the higher magnetic moment of Mn 2+ in the ZnFe2O4 lattice and also the distribution of cations at tetrahedral (A) and octahedral (B) sites. Photocatalytic degradation (PCD) of methylene blue (MB) using spinel MnxZn1−xFe2O4 (0.0 ≤x≤ 1.0) nanocatalysts was carried out, and the PCD efficiency is increased with increasing Mn 2+ ions, and the sample Mn0.6Zn0.4Fe2O4 showed better efficiency than other samples, due to their smaller particle size and higher surface area.
