                      colloidally stabilized Ni nanoparticles and Pt@NiPt
                      core−shellnanoparticles with a platinum content of $4\%.$
                      Thin films of bothnanoparticle systems were deposited on
                      yttria-stabilized zirconiasubstrates by spin-coating.
                      Oxidation−reduction cycles were usedto remove oxides and
                      organics and obtain metallic particles. Thecycling
                      conditions necessary to clean and reduce Pt@NiPt
                      core−shell nanoparticles were milder than for the Ni
                      nanoparticles,which also needed several cycles to burn off
                      residual organics.During cycling, the Ni nanoparticles lost
                      their initially epitaxialrelationship with the substrate and
                      adopted a random orientation,while no epitaxial orientation
                      was observable for the core−shellnanoparticles. Reasons
                      for this are discussed together with theinfluence of
                      platinum on Ni reduction. The Ni and Pt@NiPt nanoparticles
                      sintered during the process but retained crystallinedomain
                      diameters close to the original particle diameters. Our
                      results show that colloidally stabilized nanoparticles can
                      be transferredonto a technologically relevant substrate and
                      be reduced to metallic nanoparticles. The fabrication and
                      final structures are discussedas a feasible route to realize
