摘要

Graphene oxide sheets have been used as a kind of plane stabilizing agent to prepare Ag nanoparticle colloids. The utilization of graphene oxide has effects on the size of Ag nanoparticles and can enhance the stability of the as-prepared colloids. These graphene oxide stabilized Ag nanoparticles possess relatively uncapped surface, which behave good catalysis activity. Furthermore, we also prepared graphene oxide-mediated Au and Pt nanoparticle colloids through galvanic replacement reactions using graphene oxide-Ag nanoparticles as templates.
