Morphology and structural stability of Pt–Pd bimetallic nanoparticles |
Atomic structures of (a) SP, (b) TO, (c) CU, (d) TH, (e) OH, and (f) RD shapes. The first, middle, and last two columns show small (0.2), medium (0.5), large (0.8) Pt compositions, respectively. For each of the two columns, the first and second columns, respectively, represent the whole and cross-section atomic arrangements of alloy nanoparticles. Pt atoms are in purple, and Pd atoms are in green. |
