Thermal Decomposition of Copper Acetate at Various Temperature and Time to form Copper Oxide/Copper Nanoparticles

Abstract

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