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.
