Nanotechnological Applications of Nickel Oxide Nanoparticles and its correlation with Structural and Magnetic Properties

Abstract

  “Nano nickel oxide was synthesized by the precipitation method and characterized by the use of XRD (X-ray diffraction), TGA / DTA, TEM (transmission electron microscopy) and magnetic measurement techniques. XRD studies show that nickel oxide formed as NiO and has an octahedral structure. Magnetic measurements showed that nickel oxide has two unpaired electrons and is paramagnetic in nature. The particle size of the synthesized iron oxide was determined by TEM. The TEM images show that the particle size of NiO ranged from 28 nm to 52 nm, which is in good agreement with the theoretically predicted dimensions of the nanomaterials. This method is cost effective, easy and efficient compared to known nanomaterial synthesis methods such as thermal decomposition of precursors, metal and oxygen ion co-implantation, and ultrasonic spray pyrolysis.”
