Synthesis of porous Ag–Ag2S@Ag–Au hybrid nanostructures with broadband absorption properties and their photothermal conversion application

Synthesis of Pd–AuAg trimetal nanohybrids with controlled heterostructures and their application in the continuous flow catalytic reduction of Cr(vi)

“…The standard reduction potential of Ag + /Ag is 0.8 V relative to the standard hydrogen electrode (SHE), which is lower than that of AuCl 4 − /Au (1.0 V vs. SHE). Therefore, the reduced Ag atoms are rapidly oxidized and Au 3+ ions can be further reduced without the action of the reducing agent (PVP) because of the following reaction: 67–69 3Ag + AuCl 4 − → 3Ag + + Au + 4Cl − …”

High-yield synthesis and hybridizations of Cu microplates for catalytic applications

“…When a HAuCl 4 aqueous solution was added to the aqueous dispersion of Cu microplates synthesized in the presence of acetonitrile, the aqueous dispersion changed from brown to blue-gray, indicating that the galvanic replacement reaction occurred immediately. 86,87 Fig. 6(a) and (b) shows SEM images of the resultant Cu–Au hybrid nanostructures prepared after the addition of an aqueous HAuCl 4 solution.…”

Size-Tunable Yolk–Shell Gold–Silver Nanostructures for Photothermal Treatment of Multidrug-Resistant Bacteria

“…It is well-accepted that Au and Ag are two typical plasmonic metals that display unique resonant responses of their free electrons to the electric field of visible and near-infrared light . Such physiochemical properties make them ideal candidates as photothermal materials that efficiently absorb incident light for further conversion. − Meanwhile, the chemical stability of Ag can be enhanced by alloying with Au, which benefits their practical applications …”
