We present the development and application of a high-accuracy embedded atom method (EAM) potential for the simulation of metal alloy nanoparticles. The potential was parametrized by a large set of density functional theory (DFT) calculations of bulk metals and metal particles, including both single metals and alloys. The EAM potential accurately reproduces bulk and cluster properties, such as heats of formation and geometries. The potential is particularly useful for computationally screening a large number of different binary and ternary alloy particles for desired surface properties.
