The formation of Copper Oxide Nanorods in the Presence of Various Surfactant Micelles

Copper oxide nanorods with average diameters and lengths of ca. 8 nm and 400 nm, respectively, have been prepared by a simple onestep solid-state reaction in the presence of various surfactant micelles. The effect of three different surfactants viz., SDS, CTAB and Triton X-100 and their critical micellar concentration (CMC) on the formation of nanorods has been studied using XRD, TEM, DSC and XPS techniques. It is found that the formation of the nanorods in the presence of SDS micelles is better with higher thermal stability and possessing lower binding energy with regard to Cu_2p peak.
