3D Flowerlike Copper Sulfide Nanostructures Synthesized from Copper (I) Oxide Hollow Microspheres

In the present work, 3D flowerlike CuS nanostructures were synthesized via a facile hydrothermal process using Cu2O hollow microspheres as templates. Reaction of Cu2O hollow microspheres with thioacetamide at 40 °C for 2 h followed by hydrothermal treatment at 120 °C for 12 h resulted in high yield of 3D flowerlike structure with diameters ranging from 200 to 300 nm. The Influence of experimental parameters on the morphology of the CuS nanostructures was investigated in detail. Different stages of the formation process were studied and thus the formation mechanism of the 3D flowerlike CuS nanostructures was presented.
