Direct Electrodeposition of Graphene Enabling the One‐Step Synthesis of Graphene–Metal Nanocomposite Films

Abstract: A graphene–Au nanocomposite is prepared by a one‐step electrodeposition technique directly from a dispersion containing graphene oxide (GO) and HAuCl4. The electrodeposited graphene and Au particles are assembled into layered nanostructures. The coelectrodeposition technique can be extended to the fabrication of various graphene‐based composites.

“…Most of the existing reports focus on the deposition of nanoparticles of noble metals and oxides, like Au, Pt, Ag and TiO 2 , on the surface of GNSs to impart new functionalities, such as catalytic, energy storage, photocatalytic, sensory and optoelectronic [8][9][10]. Several papers have recently been published on simulation of the GNS/metal (Al, Cu, Ni) interfacial structure and prediction of the mechanical properties of GNS/Al [11][12][13].…”

“…As shown in Figure 1a, the cathodic peak at À1.3 V was attributed to the electrochemical reduction of GO. The successive increment of reduction current with each cycle demonstrated that the persistent deposition of conductive graphene on GCE surface was achieved [23]. In the presence of AuCl À , the AuNPs was formed by electro-reduction in this process.…”

“…Compared with the vapor deposition, electrodeposition has merits such as only needing simple equipment, easy operation and low cost. Compared with DC deposition, the current density of AC pulsed electrodeposition is higher and the nucleation rate is faster, which promotes grain refinement and is conducive to the formation of nano-materials [4].…”
