Fig. 3. TEM images of the typical porous rhombic dodecahedral AuPt@Pt bimetallic NCs obtained using the standard procedure at different reaction times, (a) 1 min, (b) 5 min, (c) 10 min and (d) 1 h, showing the evolution of morphology with time. (e) A schematic illustration showing the formation process of the Au–Pt bimetallic NCs.
