【摘要】 石墨烯是最薄的二维材料,具有极大的比表面积,可以作为纳米颗粒的基底.将氧化石墨烯和金属纳米颗粒进行复合,发挥二者的协同作用,是一种拓展和增强这2种材料性能的优选方法.本文将乙酸铅引入分散在水中的氧化石墨烯体系,获得了负载铅纳米复合材料,发现在该体系中氧化石墨烯的还原性也得到了发挥.更多还原

【Abstract】 Graphene is the thinnest two-dimensional material,and its large specific surface area makes it ideal substrate material for nanoparticles.Preparation of graphene oxide(GO)/metal nanoparticles composite,to utilize their synergistic effect,is an optimal strategy for developing and enhancing both materials.Here we report the preparation of Pb-graphene nanocomposites by introducing lead acetate into a GO-dispersed aqueous system,in which GO takes a reducing agent role as heating.更多还原
