Synthesis of CuS nanorods by one-step reaction

A one-step, solid-state reaction route was developed to synthesize copper sulfide (CuS) nanorods via grinding Cu(NO3)(2)(.)3H(2)O and Na(2)S(.)9H(2)O in existence of ethylenediamine tetraacetic acid disodium salt (Na(2)EDTA-2H(2)O) at ambient temperature. The as-prepared CuS nanorods have diameters of 5 similar to 7 run, lengths up to 40-70 nm. Transmission electron microscopy (TEM) and X-ray diffraction (XRD) were used to characterize the obtained product. A possible reaction mechanism was discussed at the end of this article.
