Synthesis of graphene decorated with silver nanoparticles by simultaneous reduction of graphene oxide and silver ions with glucose

Nanocomposites of graphene oxide, Ag nanoparticles, and magnetic ferrite nanoparticles for elemental mercury (Hg0) removal

“…GO-Ag composites were synthesized according to a revised procedure based on a previous report 30 and briey described as follows: a homogeneous aqueous mixture of GO (0.5 mg mL À1 , 100 mL) was obtained aer 45 min ultrasonical exfoliation. Then, PVP solution (4 mg mL À1 , 20 mL) and glucose (1.6 g) were added sequentially under vigorous stirring.…”

“…via oxygencontaining functional groups) and second-stage in situ reduction of the ions as well as crystallization of the Ag and iron oxides NPs. [30][31][32] The Fast Fourier Transformation (FFT) pattern (Fig. 1e) of selected nanoparticles highlighted in the red rectangular region of Fig.…”

Influence of electrolessly silver-plated multi-walled carbon nanotubes on thermal conductivity of epoxy matrix nanocomposites

“…There is also a strong interaction among the Ag nanoparticles [27]. In addition, a 0.2 eV shift to a higher BE (Fig.…”

Synthesis of nano-Cu/graphene oxide composites by supercritical CO2-assisted deposition as a novel material for reducing friction and wear

“…During the scCO 2 -assisted deposition process, the functional groups such as oxhydryl, carboxyl and epoxy group on GO surfaces adsorb positive Cu 2+ and then are reduced by DMAB, resulting in the increase of defects on GO surface. At the same time, the electromagnetic and chemical enhancement effect caused by the anchored Cu nanoparticles results in the strong D and G band intensity for Sc-Cu/GO nanocomposites [31].…”

“…Carbon (0 0 1) characteristic peak of GO at 10°is strong in the patterns of GO. This diffraction peak becomes weak in the pattern of Sc-Cu/GO composite, which mainly derives from the reduction of a few oxidative groups on GO surface during deposition process[31].The main diffraction peaks at 43.4°, 50.6°, and 74.3°in the pattern of Sc-Cu/GO composite are indexed to the (1 1 1), (2 0 0), (2 2 0) crystalline planes of Cu phase (JCPDS Card No. 03-1005), indicating that the anchored Cu nanoparticles are FCC structure.…”
