“…The SEM image in Figure 2a shows that the applied procedure of oxidation and reduction leads to the preparation of RGO material with well-shuffled graphene sheets originating from successful exfoliation of graphite precursor. The morphology of the obtained RGO is similar to that obtained by other procedures [24]. Figure 2b,c represents the composites' morphology of Cu-RGO and Ag-RGO, respectively.…”

In the present study, we report on the facile prepared nanocomposites of reduced graphene oxide RGO with Cu and Ag. The synthesis was performed through an environmentally friendly and easy method by simultaneous reduction in solutions containing Cu2+ or Ag+ and graphene oxide (GO) using zinc powder as a reducing agent in aqueous acidic media. The composites are characterized by powder X-ray diffraction, low-temperature nitrogen adsorption, X-ray photoelectron and FTIR and Raman spectroscopies, as well as Scanning and Transmission electron microscopies. The antibacterial activity of the composites was tested for Staphylococcus aureus, Escherichia coli and antifungal activity for Candida albicans. The cytotoxicity of the materials was studied towards two types of eukaryotic cells—MDCK II and A549 cell lines. The composites obtained consist of homogeneously distributed Cu and Ag nanoparticles on the surface of graphene sheets and manifest good antimicrobial activity and high cytotoxicity. The results clearly show that both metal–RGO composites can be successfully used as antimicrobial and anticancer agents.

“…[ 30,32‐35 ] In addition to the aforementioned methods, the electrochemical method is also highly suitable for the synthesis of RGO–metal oxide composites. [ 36 ] One‐step electrochemical approaches, which consist of the simultaneous deposition of GO and metal oxide, commonly include chemical reducing agents and organic linkers. [ 37 ] Electrochemical methods attracted considerable attention because of their low cost, simplicity, and facile technique.…”

For the first time, the electrochemical growth of reduced graphene oxide/cuprous oxide (Cu2O) (ERGO/Cu2O) nanostructures on indium tin oxide (ITO) electrode is induced by a new approach based on simultaneous coreduction of copper ions and graphene oxide (GO) from an aqueous suspension without using any binders, surfactant, and reducing reagents. Characterization of ERGO/Cu2O nanocomposite films is carried out using X‐ray diffraction (XRD), X‐ray photoelectron spectroscopy (XPS), energy‐dispersive spectroscopy (EDS), and scanning electron microscopy (SEM) techniques. The p‐type semiconductor of Cu2O‐decorated ERGO nanosheets is used as a photocatalyst for efficient solar hydrogen production under visible‐light irradiation. The ERGO/Cu2O nanocomposite electrode exhibits a good photocatalytic activity toward photovoltaic applications in terms of high current density (4.3 mA cm−2), which is ≈40 and 800 times higher than those of the Cu2O‐ and ERGO‐modified ITO electrodes, respectively. The resulting ERGO/Cu2O nanocomposite photoelectrode exhibits good photovoltaic properties and can be used for applications in solar energy conversion.
