Abstract

The global optimization of subnanometer Ru−Pt binary nanoalloys in the size range 2−8 atoms is systematically investigated using the Birmingham Parallel Genetic Algorithm (BPGA). The effect of size and composition on the structures, stabilities and mixing properties of Ru−Pt nanoalloys are discussed. The results revealed that
the maximum mixing tendency is achieved for 40−50% Ru compositions. Global minimum structures show that the Ru atoms prefer to occupy central and core positions and maximize coordination number and the number of strong Ru−Ru bonds.
