synthesis and characterization of lance-shaped cuo nanostructures

in the present work, we have synthesized the lance-shaped cuo via a simple and cost-effective method using copper sulfate and ammonia solution (28 wt%) as starting materials. the prepared powder was calcined in different temperatures and calcination times. it was found that the morphology of the obtained structure depends strongly on the calcination time and temperature. phase analysis was carried out using x-ray diffraction (xrd). the morphology was characterized by scanning electron microscopy (sem) and energy dispersive x-ray spectroscopy (eds). this lanced shaped cuo nanomaterial may have some potential value in nanoscale applications.
