In recent years, there have been great interests in the fabrication of coaxial nanocable-like one-dimensional (1D) structures, which combine the different types of nanotubes and nanowires in axial or radial directions [1,2]. Furthermore, as the demand for fabricating special nanowire structures increases, to develop the method not only for synthesizing a wide variety of nanowires but also for modifying or improving the properties of as-synthesized nanowires becomes very important. In the present study, we have fabricated the core-metal shell heteronanowires by using the sputtering technique. Metal nanostructures have attracted considerable attention from materials scientists on account of their application to many areas of fundamental and technical importance [3]. In addition, we have carried out the thermal annealing, generating metal nanoparticles on the surface of core nanowires. We have carried out experimenst for evaluating the catalytic effect of metal nanoparticles. We believe that the fabrication of metal  nanoparticles on core nanowires will encourage their use in various areas including heterogeneous catalysis.
