Abstract
Co-precipitation method has been used for the synthesis of single crystalline Nickel (II) Oxide sub-micro rods. A two-step method was used to synthesise NiO sub-micro rods, in which the first step was the co-precipitation process Nickel (II) Nitrate with Ammonium Oxalate to form Nickel (II) Oxalate (NiC2O4), which is the precursor for the precipitates. The precipitate precursor then underwent the calcination process to form NiO sub-micro rods. Synthesized materials undergo Field Emission Scanning Electron Microscope (FESEM), particle size measurement via Zetasizer, elemental analysis via Energy-Dispersive X-ray Spectroscopy (EDX), Fourier Transform Infrared Spectroscopy (FT-IR) and Thermogravimetric Analysis (TGA). The morphology of NiO is found to have uniform rod- like crystals with mean z-diameter between 1600 nm to 2600 nm using Zetasizer.
