CuO three-dimensional flowerlike nanostructures: controlled synthesis and characterization

CuO three-dimensional (3D) flowerlike nanostructures are synthesized on copper surface by a simple solution method and the CuO nanostructure is studied. The factors controlling the morphology and size of the CuO nanostructures are explored, which has shown that the reaction time and the concentration of starting regents have played vital roles in the formation of the CuO 3D nanostructures.
