Abstract
The (Cu-ZnO)@C core-shell nanoparticles were prepared by carbonization of Cu2+- and Zn2+-CD (Cu/Zn ratio=l; (Cu+Zn)/CD=3) at 573 K for 2 hrs. By X-ray absorption and diffraction spectroscopies, the major compounds in the Cu-ZnO@C core-shell nanoparticle are metallic copper (Cu) and ZnO. Cu20 is not observed. The TEM images indicate that the (Cu-ZnO)@C core-shell nanoparticle have the average Cu diameter of 20 nm, which are nearly in a spherical shape and isolated individually. After etching of Cu from the (Cu-ZnO)@C, the sizes of Cu encapsulated within the carbon-shell has reduced to 3-14 nm in diameters to form Cu-ZnO@C yolk-shell nanoparticles.
