Abstract

The microemulsion method is one of the effective methods for preparing nanoparticles in recent years. It has the advantages of simple apparatus, easy operation and controllable particle size. The precursors of NiO nanoparticles were successfully prepared in TritonX-100/n-hexanol/cyclohexane/water W/O microemulsion system using nickel chloride and ammonia water as raw materials. NiO nanoparticles were obtained after heat treatment of the precursors. The effects of heat treatment on the morphology and size distribution of NiO nanoparticles were systematically investigated. The result showed that the size, morphology and dispersion of NiO nanoparticles in the microemulsion state were much better than that in the state after heat treatment. XRD and TEM also showed the size of the NiO nanoparticles increased largely with the increase of heat treatment temperature.
