“…This is because Pd atoms are larger than Co atoms and the surface energy of Pd is lower (2100 mJ m À2 ) than that of Co (2550 mJ m À2 ). 45,46 Likewise, the enthalpy of sublimation (376 kJ mol À1 for Pd, 426 kJ mol À1 for Co) favors a Pd-rich surface. 47 It stands to reason that 800 C reduction results in the formation of Co-Pd alloy with surface enrichment in Pd.…”
