Metal nano particles such as Cu, Ag, and etc. are synthesized by using polyor method. And nano particles are coated by nm thickness of polymer layer with organic coating materials to prevent oxidation via dry evaporation system. This study include the graphene converting by a solid carbon source in order to overcome the disadvantage of gas carbon source. All nanomaterials can be made by polyol method with applying conversion method of graphene. All transition metals are used as the catalyst of graphene, this method will be applicable to a wide area of research.
