An Ideal Nanoreactor for Different Architectures of Core-Shell, Alloy, Individual Nanoparticles |
| 초록 |
We report on synthesis of stable polyelectrolyte complexes (PECs) in aqueous solution, acting as an ideal nanoreactor for synthesis of Au-Ag core-shell as well as Au-Ag alloy nanoparticles. The nanometer-sized PECs (composed of PAH1/PAA0.4) were synthesized by simple mixing of two weak polyelectrolytes, poly(allylamine hydrochloride) (PAH) and poly(acrylic acid) (PAA) in nonstoichiometric ratio (PAH:PAA= 1:0.40) without using sacrificial templates. Subsequently, Au and Ag precursors were loaded on PECs using as nanoreactors for synthesis of core-shell and alloy structures, followed by a successive reduction and a coreduction method, respectively. |
