Abstract：In this paper, graphene oxide was synthesized by Hummers method. And then, carboxylic acid functionalized graphene (graphene-COOH), thiol-functionalized graphene (graphene-SH) and highly dispersive graphene were prepared by chemical modification of respective groups on the graphene surface. Furthermore, we explore a solution-based approach to prepare three differently functionalized graphene-gold composites by one step chemical reduction of AuCl4- ions in functionalized graphene suspensions, where the gold nanoparticles were deposited on the functionalized graphene surface during their synthesis process. In addition, we compare the influence of surface functionalization on the growth of gold nanoparticles on graphene. Transmission electron microscopy (HR-TEM) and ultraviolet-visible (UV-Vis) spectroscopy were employed to study the effect of surface functionalities on AuNPs distribution onto the graphene surface and demonstrate the successful immobilization of AuNPs on graphene surface.

摘要：本文用Hummers方法合成了氧化石墨烯。随后通过在石墨烯表面化学修饰官能团的方法制备了羧基化石墨烯、巯基化石墨烯和高分散石墨烯溶液。此外，本文用一步化学还原氯金酸方法制备了三种不同功能化石墨烯-金复合物溶液，金纳米颗粒沉积在石墨烯表面。采用TEM、UV-VIS方法研究了表面官能化对金纳米颗粒沉积在石墨烯表面的影响，并证明了金纳米颗粒成功的修饰石墨烯层表面。
