Nanoparticles of metal and metallic oxides have be come a very active research area in the field of material chemistry. The surfac e effect is mainly responsible for deviation of the properties of nano-materials from that of the bulk. Nanosize copper oxide was synthesized by hydrolysi s of copper salts in basic medium using biodegradable non-ionic polymer polyethylene glycol (PEG) as surface active agent The X-ray powder diffraction p atterns (XRD) present typical peaks of copper oxides formed. The transmission electron microscopy (TEM) and scanning electron microscopy (SEM) images determined the shape and the nanosizes of th e particles of about 10-30nm. The results exhibited the role of intermediate nanosize copper hydroxide species on the formation of copper oxide nanoparticles. The influence of synthesis temperatu re, reaction time, calcination temperature, etc. wa s studied.
