In the present study, the copper oxide and copper nanoparticles were prepared by thermal decompositionof solid phase copper acetate at various time (1-3 h) and temperature (200-500 ºC). The method issimple, less expensive, avoid toxic solvent as well as avoid use of passivating agents. The FT-IR spectrumof the copper acetate monohydrate (calcined) shows the major changes in absorption peaks associatedwith methyl, carbon-oxygen double bond, carbon-oxygen single bond and copper-oxygen bondfunctional groups. Thermogravimetry analysis shows that the copper acetate monohydrate decomposesat about 250 ºC to form copper. The TEM images show a combination of shapes, which includesicosahedrons, truncated cubes and nano-whiskers made from sphere with diameter of 7.43-0.83 nm.
