Improved surface-enhanced Raman scattering based on Ag–Au bimetals prepared by galvanic replacement reactions

One-step electroless deposition of Pd/Pt bimetallic microstructures by galvanic replacement on copper substrate and investigation of its performance for the hydrogen evolution reaction

“…Recently, it has been proved that this simple and spontaneous process is an attractive approach for the growth of structures directly on metal or semiconductor substrates such as deposition of Au on Si [2], Ag/Pd on Si [3], Cu on Si [4], Pt on Ti [5], Au on Ge [6], Pt on Ge [7], Cu on TaN [8], Cu on Al [9], Zn on Al [10], Ni on Al [11], Pd on Ag [12], Pt/Au on Cu [13], Au on Cu [14], Ag on Cu [15] and Au on Ag [16] and other combinations.…”

A one-pot synthesis of colloidal Ag–Au nanoparticles with controlled composition

“…Currently, systems consisting of precious metal-based nanoparticles with intensive absorption bands in the visible optical region are widely employed in a vast variety of practical applications. Gold and silver nanoparticles exhibiting surface plasmon resonance (SPR) are of practical interest due to the possibility to tune the spectral position and SPR amplitude by changing composition, size, shape, structure and dielectric surrounding of the nanoparticles [1][2][3][4][5]. From the practical standpoint, aside from the morphology and size of such nanoparticle their composition is also a crucial parameter.…”

Nanoparticles and intracellular applications of surface-enhanced Raman spectroscopy

“…1D). In this approach, porous/hollow Au nanocages were obtained via a previously established galvanic replacement reaction [36][37][38] of Ag nanocubes with HAuCl 4 at their surface.…”
