“…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.…”

“…This method simplified the fabrication procedure, and could produce homogeneous and thickness-controllable AuNPs-RGO composite film. Moreover, electrochemical deposition method avoided the usage of highly toxic chemicals in chemical and thermal methods for the reduction of graphene oxide [23][24]. After the preparation of AuNPs-RGO composite, the L-cysteine monolayers assembled on AuNPs by gold-sulfur (AuÀS) bond.…”

Glassy carbon electrode (GCE) modified with L-cysteine and gold nanoparticles-reduced graphene oxide (AuNPs-RGO) composite was fabricated as a novel electrochemical sensor for the determination of Cu 2 + . The AuNPs-RGO composite was formed on GCE surface by electrodeposition. The L-cysteine was decorated on AuNPs by self-assembly. Physicochemical and electrochemical properties of L-cysteine/AuNPs-RGO/GCE were characterized by scanning electron microscopy, atomic force microscopy, energy dispersive spectroscopy, Raman spectroscopy, X-ray diffraction, cyclic voltammetry and adsorptive stripping voltammetry. The results validated that the prepared electrode had many attractive features, such as large electroactive area, good electrical conductivity and high sensitivity. Experimental conditions, including electrodeposition cycle, self-assembly time, electrolyte pH and preconcentration time were studied and optimized. Stripping signals obtained from L-cysteine/ AuNPs-RGO/GCE exhibited good linear relationship with Cu 2 + concentrations in the range from 2 to 60 mg L À1 , with a detection limit of 0.037 mg L À1 . Finally, the prepared electrode was applied for the determination of Cu 2 + in soil samples, and the results were in agreement with those obtained by inductively coupled plasma mass spectrometry.

“…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].…”

-Ni/GO nanocomposites were prepared with an AC pulse electro-deposition method. The morphologies of the deposits, crystal structure and mechanical properties of the nanomaterials were examined using scanning electron microscope (SEM), X-ray diffraction and a tensile testing machine respectively. Studies show that the addition of graphene oxide (GO) results in nano-particles of electrodeposited Ni aggregating to form micro-convexes for which (2 0 0) plane is the preferential growth orientation, accelerating the growth of nucleus, improving the crystallization and inhibiting the growth of grain. The room-temperature tensile elongation was up to 9.89% when GO = 0.1 g/L; the breaking strength reached 625 MPa when GO = 0.03 g/L; the tensile elongation in 450°C was 232%, which presents a good superplasticity when GO = 0.08 g/L.
