提出了一种通过羟基官能化氧化石墨烯(GOSH)与金纳米颗粒(AuNPs)之间的Au-S键合成金纳米颗粒-石墨烯杂化产物(AuNPs-GOSH)的方法。在这种方法中，高度分散在GOSH纳米片上的羟基被用来组装金纳米颗粒，形成AuNPs-GOSH杂化材料。结果表明，Au NPs-rGO杂化材料对氧还原反应具有较高的电化学活性，在碱性介质中具有较高的稳定性。(C)2013爱思唯尔B.V.保留所有权利。
An approach to the synthesis of gold nanoparticles-graphene (AuNPs-GOSH) hybrids via the Au-S bond between the sulfhydryl-functionalized graphene oxide (GOSH) and gold nanoparticles (AuNPs) has been proposed. In this approach, the sulfhydryl groups highly dispersed on the GOSH nanosheets are used to assemble gold nanoparticles, forming the AuNPs-GOSH hybrids. It is found that the AuNPs-rGO hybrids show high electrochemical activity toward the oxygen reduction reaction (ORR) and high stability in alkaline media. (C) 2013 Elsevier B.V. All rights reserved.
