Synthesis and characterization of composite of gold nanoparticles attached ZnO nanorods

Abstract

We report on the growth and characterization of ZnO nanorods using chemical vapor deposition (CVP) with and without graphite, wet chemical reaction and gold attached ZnO nanorods called nanocomposites. Various novel arrangements of growth of uniform one dimensional ZnO nanostructures were observed. The ZnO nanostructures and the composite materials were examined by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), The results of characterization demonstrated that ZnO nanostructures are one dimensional, the nanocomposites consist of both gold nanoparticles and ZnO nanorods. The result also shows that the gold nanoparticles were tightly attached on the nanorod surface. Our results suggest that ZnO nanostructures and nanocomposites are useful for solar cell, sensor applications. The detail of the results will be presented.
