摘要 以氧化石墨为原料,采用光还原法先将金属Co沉积于石墨烯表面,然后将其加入Ru Cl3水溶液中,金属Co氧化产生的电子通过石墨烯传递到Ru^3＋,并将其还原得到Ru-石墨烯。用透射电子显微镜（TEM）、X射线衍射（XRD）等技术对Ru-石墨烯复合材料进行了表征测试。结果表明,在用这种方法制备的Ru-石墨烯复合物中,沉积于石墨烯表面的Ru纳米粒子粒径小并且分布均匀,粒径分布在1-1.5nm范围内。该研究为合成Ru-石墨烯提供了新途径,同时也进一步证明了石墨烯优良的传递电子功能。 Graphite oxide taken as raw materials,Co is deposited on the surface of graphene through light reduction method and then Co / graphene is added to RuCl3 aqueous solution. The electrons of metal Co transfers to Ru^3＋through graphene sheets,and Ru^3 ＋is reduced to form Ru / graphene nanohybrids. The structure of Ru / graphene is characterized through transmission electron microscopy（ TEM）,X-ray diffraction（ XRD）. The results indicate that Ru nanoparticles on the surface of graphene has relatively uniform size,and the diameter of it is in the range of 1 -1. 5 nm. This research provides a new method to generate Ru / graphene and demonstrates the electron function of graphene.
