Efficient degradation of azo dyes using Ag and Au nanoparticles stabilized on graphene oxide functionalized with PAMAM dendrimers

Graphene Dendrimer-stabilized silver nanoparticles for detection of methimazole using Surface-enhanced Raman scattering with computational assignment

“…It suggests that the AgNPs are stabilized in the G-D network through this functional group25. The disappearance of the peak, attributed to C-O at 1324 cm −1 in the G-D-Ag spectrum, is probably due to the reduction of the oxygenated functional groups through the heat treatment process15.…”

Photocatalytic activity of biogenic silver nanoparticles synthesized using potato (Solanum tuberosum) infusion

“…The created hydroxyl radicals further oxidize methyl orange molecules adsorbed on the surface of the Ag nanoparticles into its degradation by-products [42]. Hence, for degradation of organic dyes under visible light irradiation, silver nanoparticles may be used as highly stable and effective photocatalysts [43].…”

Iron nanoparticles decoration onto three-dimensional graphene for rapid and efficient degradation of azo dye

“…The use of zero-valent metals for dyes degradation, as an emerging technology, has also attracted increasing attentions recently. Some noble metals such as Ag, Au and Pd have been reported as the catalysts for dyes decolorization under borohydride reduction conditions [5][6][7]. The zero-valent Mg based systems were also found to efficiently decolorize various azo dyes [8].…”
