In nanocatalysis, a great challenge is to obtain truly homogenous and well-defined highly active
nanostructures on surfaces. Ligand protected metal nanoclusters is an emerging class of functional
nanomaterials consisting of less than 100 atoms, with atomic precision, well-defined molecular
structure. These properties are also sensitive to the metal composition, which allows tuning
properties by removing, adding or replacing (doping) one
or more au atoms with heteroatoms. We successfully
doped different cluster sizes by metal as Pd, Pt, Cu or Ag,
producing bimetallic and trimetallic nanoclusters with
atomic precision. Insights in the structural and properties
changes were obtained by several spectroscopic studies
(XAFS, XPS, MALDI...) correlated with DFT
calculations[1, 2].
