Influence of pH on Hydrothermal Synthesis and Properties of Copper Ferrite Nanoparticles

Pure cubic-shaped copper ferrite nanoparticles with crystallite size of 39 to 56 nm were prepared by hydrothermal method under different reaction and annealing temperatures. The lattice constant, microstrain, and dislocation density are determined using XRD. FTIR spectra exhibited the presence of me...

Description
Summary:Pure cubic-shaped copper ferrite nanoparticles with crystallite size of 39 to 56 nm were prepared by hydrothermal method under different reaction and annealing temperatures. The lattice constant, microstrain, and dislocation density are determined using XRD. FTIR spectra exhibited the presence of metal oxides at tetrahedral and octahedral sites. The images of FESEM and HRTEM confirmed the irregular spherical and cubic-shaped structure. Compositional features are determined from EDX analysis. Magnetic studies were carried out using AVFTB at room temperature, and the various parameters were measured from the hysteresis curves. A transition from soft ferromagnetic to hard ferromagnetic behavior was noticed with increase of annealing temperature. The electrochemical analysis revealed the pseudocapacitive nature with high specific capacitance at low scan rate. Graphical Abstract
