On the structure of bimetallic noble metal nanoparticles as revealed by aberration corrected scanning transmission electron microscopy (STEM)

Journal Article


Abstract


  • 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.
