| Description |
Shape-selective formation of CoO nanoparticles
has been developed using a simple one-step
in situ non-micellar microwave (MW) heating
method. CoO NPs were synthesized by mixing
aqueous CoCl26H2O solution with poly (vinyl) alcohol
(PVA) in the presence of sodium hydroxide
(NaOH). The reaction mixture was irradiated using
MWfor a total time of 2 min. This process exclusively
generated different shapes like nanosphere, nanosheet,
and nanodendrite structures just by tuning the Co(II)
ion to PVA molar ratios and controlling other reaction
parameters. The proposed synthesis method is efficient,
straightforward, reproducible, and robust. Other
than in catalysis, these cobalt oxide nanomaterials can
be used for making pigments, battery materials, for
developing solid state sensors, and also as an anisotropy
source for magnetic recording
