In the present manuscript we present the feasibility of two different routes to obtain metal nanoparticles: (1) inert gas deposition technique (IGC) and (2) chemical routes. These two routes can enable the production of metal nanoparticles with a well-controlled size and shape distribution. In addition, Co/Au and Pd/Au nanoparticles have been deposited on three different grids with the aim of studying the coalescence of the different metals. The as-synthesized materials, that initially were forming isolated, core–shell, were sintered by thermal treatment (Co/Au) or by strong electron beam irradiation and the subsequent characterization was carried out in situ in an aberration corrected STEM.
► Bimetallic nanoparticles have been produced by a physical method and by a chemical method. ► The different structures formed by each technique have been analyzed with atomic resolution by aberration corrected transmission electron microscopy. ► The coalescence of different metal nanoparticles has been produced via thermal annealing or by electron irradiation. ► For this reaction it was found that Au was always at the core of the final product.
