Abstract

Copper nanoparticles have been successfully synthesized by using low auto-combustion synthesis method followed by
calcination at 500 oC for two hours. The calcined copper oxide nanoparticles were investigated by various tools such as
XRD, DRS, FT-IR and HR-TEM. The characteristic absorption peak at 535 cm-1
corresponds to copper-oxygen
stretching vibration mode of copper oxide. The HR-TEM micrograph of the obtained copper oxide sample reveals the
spherical nanoparticles with soft agglomeration and the average particle size calculated from TEM-image is about 35 nm
for CTA sample.
