Abstract
Nickel ferrite (NiFe2O4) Nanoparticles have been synthesized by a simple surfactant-free electrochemical method at room temperature using iron plates as the cathode and anode electrode. nickel sulfate hexahydrate solution used as the electrolyte has a concentration of 0.04 M and pH 10. The voltage applied varied from 6, 9, and 12 V. We found that voltage and hydroxyl ions (OH-) presence have an important role in the formation of nickel ferrite nanoparticles. Particle size can be controlled by voltage. Nickel ferrite nanoparticles were produced in the form of gray powder and exhibited ferromagnetic properties. Material produced exhibits spinel oxide characteristics that confirms nickel ferrite presence. Nickel ferrite produced are nearly spherical with narrow size distribution having the size that can be classified as nanomaterial. Good electrochemical performance is legitimately observed for NiFe2O4 prepared in this work. This simple method is promising as a facile synthesis method for nickel ferrite nanoparticles.
