【Abstract】 Hummers method which is adopted for the preparation of graphite oxide is modified and the graphene-silver nanoparticle composites are prepared by using non-toxic and green glucose as reducing agent in the absence of stabilizer and mild liquid phase reaction. The prepared graphene-silver nanoparticle composites are characterized by X-ray diffraction and infrared absorption spectroscopy. The results show that the graphite oxide and silver ions are simultaneously restored by glucose during the reaction. The dispersibility of graphene-silver nanoparticles in DMF organic solvent is better than that of graphene oxide.更多还原
