Hydrothermal synthesis of cobalt oxide nanoparticles: Its optical and magnetic properties
Cobalt oxide (Co3O4) nanoparticleshave been synthesized by hydrothermal method using mixture of cobalt(II)chloride, Triton X-100 and KOH in an autoclave at 180 °C for 6 h followed by heating at 400 ºC for 3 h in air. The product have been characterized by Fourier transform infrared (FT-IR), UV-Vis spectroscopy, powder X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission ...
متن کاملCobalt Oxide Nanoparticles: Characterization and its Electrocatalytic Activity towards Nitrobenzene†
Cobalt oxide (Co3O4) nanoparticles were successfully prepared by thermal decomposition of cobalt hydroxide synthesized from cobalt acetate, ammonium hydroxide and 10% glycerol. The cobalt oxide nanoparticles calcined at 450 °C were characterized by using XRD. The XRD confirms the crystallinity and crystal structure of the sample. It also shows that the diffraction peak are broadened which revea...

متن کاملFormation of cobalt-Prussian Blue nanoparticles in a biopolymer matrix.
The molecular magnet material, cobalt-Prussian Blue, has been synthesized using chitosan as a morphological structure-directing agent. The strong chelating ability of the biopolymer ensures that the inorganic phase remains nanoparticulate. SQUID magnetometry reveals that the nanoparticles exhibit a sharp ferrimagnetic to paramagnetic transition at 16 K.
متن کاملPreparation of Cobalt Oxide/Zinc Oxide Nanocomposite
Cobalt Oxide/ Zinc Oxide nanocomposite was synthesized by dropwise addition ofCo(NO)3.6H2O and Zn(NO3)2.4H2O solutions to KOH solution at different temperatures followed bycalcination at 300ºC for 4 h. The morphology and structure of nanoparticles and the influence oftemperature on particle size were studied using scanning electron microscopy (SEM) and X-RayDiffraction (XRD). Minimum particle s...
