Structures of small Pd–Pt bimetallic clusters by Monte Carlo simulation

Bimetallic Pt–Pd/silica–alumina hydrotreating catalysts – Part I: Physicochemical characterization

“…However, experimental and theoretical evidence for the segregation of Pd to the surface of bimetallic Pt-Pd clusters is more abundant [10][11][12][13][14][15]. Pd is claimed to segregate to the surface during thermal treatment, probably because of the different surface energy of Pt and Pd [16]. Many other factors, however, may also affect Pd migration.…”

Modification effects of magnetic supports and bimetallic structures on palladium nanocluster catalysts

“…By using the Monte Carlo (MC) simulation method based on the second-moment approximation of the tight-binding (TB-SMA) potentials, the structure of bimetallic cluster can be simulated [19]. Because the Pd-Pt cluster is synthesized in methanol-water-refluxing system, the temperature is set to be 350 K for the simulation.…”

First-principles investigations of multimetallic transition metal clusters

“…Bimetallic FePt and CoPt nanoclusters have been subject of intense experimental [40][41][42][43][44][45][46][47][48] as well as theoretical [14,[49][50][51][52][53][54][55][56] investigations, in particular because of their potential use in miniaturized storage media requiring monodisperse FePt nanoparticles and ferromagnetic FePt nanocrystal superlattices [57][58][59] and in nanocatalysis where the catalytic properties of highly dispersed supported bimetallics are used [60,61].…”
