In this study CuO nanoparticles were prepared via direct thermal
decomposition method using basic copper sulphates as wet chemically
synthesized precursor which was calcined in air at 750°C for 2h. Samples
were characterized by thermogravimetric (TG-DSC), X-ray diffraction (XRD),
energy dispersive spectroscopy (EDS), infrared spectrum (IR), scanning
electron microscopy (SEM), and transmission electron microscopy (TEM). The
XRD, EDS, and IR results indicated that the synthesized CuO particles were
pure. The SEM and TEM results showed that the CuO nanoparticles were of
approximate spherical shape, and 170±5 nm in size. Using this method, Cuo
nanoparticles could be produced without using organic solvent, expensive raw
materials, and complicated equipment.
