AbstractCarbon nanostructured materials such as carbon nanotubes and graphene are attracting much attention due to their outstanding structural and physical properties. Metal nanoparticle-decoration can provide additional functionalities to these nanocarbons. Several chemical and physical methods are being used for the synthesis of these metal-carbon nanohybrids. On the other hand, the fascinating properties of gold nanoparticles have begun to be efficiently utilized for a variety of applications such as in photonics, catalysis, and sensor devices. Therefore, gold nanoparticle decoration of carbon nanotubes and graphene can provide promising nanohybrid materials for a whole plethora of technological applcaitions. In this work, we present chemical routes for gold nanoparticle decoration of carbon supports including carbon nanotubes and graphene. Our chemical methodology allows controlling the gold nanoparticle content of the synthesized nanohybrids, the gold nanoparticle size and uniform coating on the carbon supports used. Our results show that the structural properties and dispersibility of the of the carbon supports strongly affect the gold nanoparticle decoration process, Applications for these goldnanoparticle decorated carbon nanostructured materials are presented and discussed.
