ABSTRACT While graphene has unique electrical and mechanical properties, it is not soluble in most common solvents. Partially reducing graphene oxide (prGO) will remove some of the functional groups while still maintaining solubility, producing an intermediate between graphene oxide and reduced graphene oxide. This research investigated the properties of prGO as well as those of prGO sheets incorporated with gold and platinum nanoparticles (Au/Pt-prGO) using FTIR, Raman, TEM and HRTEM. . INTRODUCTION During the process of producing graphene oxide (GO), strong oxidizing agents are used to break up the sp2 structure of the stacked graphene sheets in graphite oxide, producing oxygenated graphene sheets covered with epoxy, hydroxyl, and carboxyl groups. The new material contains a much larger interlaying hexagonal lattice structure and is now hydrophilic [1]. However, unlike graphene, GO is an insulator due to the presence of the many oxygenated functional groups. By reducing GO, most of the attached functional groups are removed, producing electrically conductive graphene or reduced graphene oxide (rGO) [2]. Graphene, a single layer of carbon atoms arranged in a hexagonal lattice structure, possesses remarkable physical and electronic properties. Graphene is currently the most electrically conductive material due to its sp2 hybridization, virtually 2D structure, and extremely large theoretical specific surface area of 2630 m2 g-1 [3]. Graphene’s unique planar structures and large surface area offer an excellent capability to immobilize a large number of substances, including metals [4], drugs [5], and biomolecules [6]. However, pure graphene is not soluble in common solvents,
