Synthesis of nano-crystalline Co3O4 particles by hydrothermal method under pulsed magnetic field
Nanocrystalline Co3O4 particles were successfully synthesized by hydrothermal method under pulsed magnetic field. The effect of magnetic field and aging time on the morphology and microstructure were examined. Different morphologies were observed from SEM images for the samples fabricated with or without pulsed magnetic field. The pulsed magnetic field made Co3O4 sphere compact and more smooth surface. The hollow sphere morphology and refined grain of Co3O4 were formed after aging process.
