Abstract :
An original physical route is proposed to organize size-selected bimetallic nanoparticles on graphite surfaces. This approach is based on the soft landing of preformed clusters and is demonstrated for bimetallic AuxPt1 − x clusters of different compositions. Particle coalescence is avoided thanks to cluster surface reactivity, leading to a self-assembly with a well-defined inter-particle separation (~ 1 nm).
