INOR 643 |
| Nickel oxide (NiO) has been under extensive investigations for decades as a kind of important inorganic material. NiO nanoparticles have attracted a great deal of attention due to both scientific interests and potential applications because of their special physical and chemical properties. The particle structural property (particle size, distribution, morphology) is closely related to the preparation technique. NiO was prepared by modified sol-gel method and spherical NiO nanoparticles were obtained. The factors that influence physical property of NiO nanoparticles were investigated mainly through the ways of SEM, BET and XRD. It revealed that calcination temperature of precursor and the pH value of solution significantly affected the particle size and surface area of the synthesized nanosized NiO powders. The ratio of citric acid to nickel nitrate and heating rate of calcinations were also important to the physical property of nanosized NiO. The length of calcinations time has minor effect on it. |
