Table 1 Atomic compositions of nanostructures obtained from galvanic replacement (GR) of Ag nanocubes by Au at 90 °C
From: Direct observation of the nanoscale Kirkendall effect during galvanic replacement reactions
Amount of 0.1 mM HAuCl 4 added (mL) | Final concentration of Au 3+ ions in solution (µM) | Atomic % of Ag in nanostructure (measured with EDX) | Atomic % of Au in nanostructure (measured with EDX) |
|---|---|---|---|
0.3 | 5.6 | 97 | 3 |
1.5 | 23 | 78 | 22 |
4.0 | 44 | 67 | 33 |
