Figure 4From: Kinetic study of Pt nanocrystal deposition on Ag nanowires with clean surfaces via galvanic replacementTEM images showing Pt nanocrystals deposited on surface of Ag wires with different reaction times. Different reaction times at 170°C, (a) 1 h, (b) 2 h, and (c) 3 h, as well as the SAED patterns of Ag core and Pt shell.Back to article page
