“…The embedment of AgNPs on graphene nanosheets may reduce the average size of in-plane sp 2 domains as they encompass a larger degree of surface area of nanometer size when compared to the molecular-sized oxygenous groups of GO. Moreover, the intensity peaks of the D and G bands were enhanced in the case of AgNPs-rGO due to the surface-enhanced Raman scattering effect of AgNPs, which is about 1700% greater than that of GO [35]. + ions than AgNO 3 , leading to creation of more initial nucleation sites [17], and 2) Ag(NH 3 ) 2 OH has a higher stability than AgNO 3 and resists reduction, hindering the growth of Ag into large particles [27].…”

Please note that during the production process errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain.1 One-step electrodeposition synthesis of silver-nanoparticle-decorated graphene on indium- AbstractSilver-nanoparticles-decorated reduced graphene oxide (rGO) was electrodeposited on indium tin oxide (ITO) by a cyclic voltammetry method. The results of X-ray diffraction, Fourier-transform infrared transmission spectroscopy and Raman spectroscopy confirmed the simultaneous formation of cubic phase silver nanoparticles and reduction of GO through the electrodeposition process. Field emission scanning electron microscope images showed a uniform distribution of nanometer-sized silver nanoparticles with a narrow size distribution on the RGO sheets, which could only be achieved using silver ammonia complex instead of silver nitrate as precursor. The composite deposited on ITO exhibited notable electrocatalytic activity 2 for the reduction of H 2 O 2 , leading to an enzymeless electrochemical sensor with a fast amperometric response time less than 2 s. The corresponding calibration curve of the current response showed a linear detection range of 0.1 mM to 100 mM (R 2 = 0.9992) while the limit of detection was estimated to be 5 µM.

“…The Raman spectrum of GO ( Fig. 2a and inset), indicates the presence of two prominent peaks at 1347 cm -1 (known as D band) and 1590 cm -1 (G band), corresponding to the breathing mode for k-phonon of A 1g symmetry and E 2g phonons of sp 2 -bonded carbon atoms respectively [18,26]. In contrast, the spectrum of G reveals the blue shift of G band to 1579 cm -1 (Fig.…”

“…As the extraordinary properties of graphene is relevant only in few layers or even more in single layer, it has recently been reported that noble metal or alloy NPs such as gold (Au), silver (Ag), platinum (Pt), palladium (Pd) [17][18][19][20] etc. can be used for the decoration of graphene sheets to prevent the agglomeration or restacking.…”

In the present investigation, graphene (G) and graphene decorated with Ag (Ag-G), Au (Au-G) metal nanoparticles as well as AuAg alloy (AuAg-G) nanoparticles (NPs) have been successfully synthesized via solution chemical route. The specimens have been characterized by using XRD, Raman, UV-Vis spectroscopy and TEM. TEM study confirms the formation of few-layered graphene sheets decorated with metal and alloy NPs. The relative change in the positions of D and G bands in Raman spectra of Ag-G, Au-G and AuAg-G as compared to graphene reveals a significant electronic interaction between graphene and metal or alloy NPs. A better electronic interaction between AuAg alloy NPs and graphene as compared to that of pure metal NPs has been shown by an enhancement in the intensities of G and D bands in Raman spectrum of AuAg-G as compared to those of Ag-G and Au-G. UV-Vis spectroscopic analysis also indicates, a larger blue shift in the absorption peak of the graphene in AuAg-G than that of metal decorated graphene, suggesting a better interaction between graphene and alloy NPs. These results indicate that alloy NPs can tune the electronic structure of graphene better than metal NPs. Such changes in electronic interaction will lead to modification of the electronic behaviour of graphene, making these materials suitable for many electronic applications.

“…The presence of quaternary nitrogen in the structure of the macromolecules enhances the bactericidal activity of the composites, while the zwitter-ionic nature of the polymers imparts resistance to the formation of bacterial biofilms. Carbon fillers are commonly used as additional inorganic components in the preparation of hybrid systems containing SN [38][39][40][41]. Electroactive nanocomposites are formed upon the reduction of the Ag + ions in a dispersion of multiwalled carbon nanotubes (MCNT) stabilized by a PEG-oligoimid block copolymer.…”

The major methods for the preparation of silver-containing polymer composite nanosystems and the formation of their hybrid structure are examined. Special attention is focused on a new class of silver-containing hybrid systems, namely, organic-inorganic coordination polymers, obtained by the self-assembly of silver complexes. The effect of intercomponent interaction on the structure and properties of these hybrid composites was examined.The creation of new improved materials is an important goal of modern chemistry and materials science. Polymer composites with hybrid structure are among such materials and hold interest since they display a combination of properties characteristic for each of the inorganic and organic components [1-3] and, in some cases, unique properties related to the specific nature of their structure [4]. From a modern viewpoint, hybrid organic-inorganic materials are formed by the combination of components, differing in their chemical nature, on a molecular or nano level through formation of chemical bonds ((non)covalent bonds, hydrogen bonding, and donor-acceptor bonds) or weaker physical bonds (van der Waals and electrostatic interactions) [5]. Special attention is given to the stability of the nanodispersed components due to interaction between the nanophase and various stabilizers [6]. The interest in silver-containing hybrid polymer composite materials, including nanocomposites, which, by their very nature, are a priori hybrid systems, is attributed to a set of properties of the matrix itself, which often possesses hybrid structure, properties of silver in ionic and nanodispersed forms, and new properties related to the appearance of hybrid silver-polymer structures [7,8]. Special interest is presently found in bionanocomposites derived from biopolymers and silver nanoparticles (SN), which display specific physicochemical properties, in particular, electrochemical, photochemical, and catalytic properties highly dependent on the dimensions and polydispersion of the nanophase [9, 10] as well as biological activity due to the ionization of the metal atoms in the presence of H 2 O/O 2 and the interaction between the SN surface and functional groups of the various biomolecules [11].In light of the important role of the polymer matrix in formation of the major structural characteristics and properties of silver-containing hybrid systems, we should classify these materials according to their chemical structure.Composites with Silver Nanoparticles (SN) Dispersed in a Polymer Matrix with Hybrid Structure. The major distinguishing feature of such materials is the prior synthesis of the hybrid polymer matrix obtained due to the formation of chemical bonds between the organic and inorganic components with subsequent introduction of SN into the system. The synthesis of the SN may be either in situ or ex situ. 740040-5760/15/5102-0074
