Investigation of mass transfer surface self-diffusion on palladium

Using corrosion to fabricate various nanoporous metal structures

“…Extrapolation to room temperature (298 K) from the literature data yields surface mass transfer diffusion coefficients of Pt, Pd, Au, and Cu of 3.6 Â 10 À22 , 1.1 Â 10 À20 , 2.2 Â 10 À19 , and 1.1 Â 10 À14 cm 2 s À1 in vacuum [65,66]. The surface diffusion of Ag is two orders of magnitude faster than that of Au in vacuum [67].…”

Interaction of Rh with Rh Nanoparticles Encapsulated by Ordered Ultrathin TiO1+x Film on TiO2(110) Surface

“…Bradshaw's model) governing this process was recently 166 analyzed in detail 46. Annealing at higher temperatures results 167 in splitting of the continuous Rh multilayer into stripe-like Rh 168 islands and leads to a TiO 2 (110) surface covered partially by Rh 169 islands exhibiting flat top facet (see below).…”

Vapor phase growth of free-standing palladium nanorods

“…5b). Comparing with the previous reports, Gjostein et al have reported the activation energy of 106 kJ/mol when the Pd atoms diffused on the surface of Pd [28,29]. Because the enclosure surfaces are very smooth, as the result, few incoming Pd adatoms will remain on the flat, low energy surfaces.…”
