ResumoNano-NiO particles have been synthesized at room temperature via single-phase precipitation, using NiCl2·6H2O and NH3·H2O as the raw materials and H2O as solvent. It has been indicated by X-ray diffraction (XRD) and X-ray fluorescence (XRF) analysis as well as transmission electron microscopy (TEM) analysis that nano-NiO particles have cubic crystal structure with about 9 nm of average diameter and 99.73% of purity. Compared with conventional methods, the developed method is simple and inexpensive so that it has potential for further scale-up application in industry. The key factor is how to control the chemical reaction in solution and competitive balance. This paper has discussed these aspects.
