NiO/ZnO Core-Shell Nanoparticles In Situ Synthesis Via Microemulsion Method

Nanoparticles of NiO(core)/ZnO(shell) core-shell and nanoparticles were successfully prepared in Triton X-100/n-hexanol/cyclohexane/water W/O microemulsion system. Basic synthesis conditions were determined. Ni(OH)(2)/Zn(OH)(2) nanoparticles were first synthesized at room temperature then calcined at 500 degrees C to form NiO/ZnO nanoparticles. The calcined products were studied by means of TEM, and XRD analyzers. The mechanism of the core shell NiO/ZnO nanoparticles formation is explained.
